Try going into your phones settings and turn Off fast charging.
Then soft reboot the phone by turning it Off and On.
Then go back into your settings and turn fast charging back On.
As a process of elimination can you try another official Samsung fast charger brick and cable.
That and or try your fast charger with another Samsung phone.
Are you able to try a wireless charging pad etc.
Have a peek in the phones charging port with a torch to see if any debris / lint has built up.
Don't use compressed air or anything sharp to clean it however.
A Samsung Service Centre or Samsung Experience Store can take a look too @Rafay_Naeem

The advice I offer is my own and does not represent Samsung’s position.

I've an issue with Samsung Note 9 fast charging. I believe, it stopped working since UI 2.x upgrade.
I've done all the options described below.
(1) Restart phone with safe mode and checked - it does show "charging" only and not "fast charging"
(2) Disable fast charging option, restart phone, enable fast charging option -- it does show "charging" only and not "fast charging"
(3) Clean charging cable area for any debris - no luck
(4) Use another cable to charge the device - no luck
What next can be done prior to "factory reset"?

I see my phone was exposed to sea water after 2 to 3 days my phone stop fast charging like when ever I plug it in it shows fast charging after 2 to 3 minutes it show charging so I tried every thing like I factory reset my phone, start my phone on safe mode but noting happened.
One of my friend told me to cover the rear speaker and s pen with a tape and wash the charging port with pressure water so I use shower head after that I use Anti-Static Tweezer and alcohol pad to clean points in charging port gently, after that my phone fast charging work. Okay one more thing if you are planning to do this note this your phone have been not opened before for any repairs because it's weaken your phone ip68 and your phone can get damage from water.

I also had this issue all of a sudden, on connecting the charger it just briefly switched to fast charging. I needed to go into setting and disable and enable fast charging 3 times in a row. Then it started working again.

Mine started doing the same and I have bought a new fast charger, rebooted, soft restart after turning fast charge off , put apps to sleep, got rid of some apps and even though with the new charger it says its fast charging, it still either stays for a long time at a certain percentage or goes down. Only sometimes going up. Also What is best way to clean port?

i also happen to find the same issue, i've tried factory reset, but the issue still prefail. However, later i accidentally found, that when you charge using type c cable and the pin's (the metal part of the cable) smooth face is facing upward (the same direction as phone's screen - imagine the phone is on the table with screen facing upward) ,its start the quick charge mode, and vice versa, when the pin's smooth side facing downward, it become slow charge. I confirm this with multiple cables and charge head. It works with mine, i hope it works for you as well.
