That's a conundrum @painter1960
Try deleting the version from your Sd card and just pick the one saved in your phone's internal memory which should have been placed in the correct internal files i.e ringtones.
Here is the route I use to change my ringtone which stays changed.
- Settings.
- Sounds and Vibration.
- Ringtone.
- Choose my saved preffered tone.
I sure your doing the same. 😉
What I would try is…
Go into Safe Mode.
Put the phone in Safe Mode which disables your downloaded app's but let's your stock app's keep working. If the issues stop then this highlights a downloaded app as the possible issue. Come out of Safe Mode and start deleting your most recent downloaded app's one at a time until it stops. https://www.samsung.com/uk/support/mobile-devices/how-to-start-my-galaxy-device-in-safe-mode/
If the tone does not still hold in Safe Mode then maybe the tone you've downloaded is somehow not fully compatible.
I use Zedge.com to get my free ringtones.
Perhaps try downloading one from their site and try that to see what happens.
I wish you all the best with this.

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