Dual SIM in Galaxy S8 plus - delete SIM2 name when SIM2 not inserted

[StoneHawk]

hello,

I have removed SIM2 physically from my Galaxy S8 plus, however  I cannot remove the SIM2 account name from "Ringtone". Also under "SIM card manager" I cannot access "call settings" to switch "Dual SIM" off.

Please advise if there's a way around that.

Thanks
