Help Strange occurrence with sounds

[markdoc]

I use a calendar app that has 5 different sounds. On my Pixel 6 Pro, I can access any app's sound settings two ways. Either through the app's settings or through the app's information in the phone's settings. (Or just long press the app's icon and choose the "circled I")
When I access the calendar's sounds, each way gives me a different list of sounds. One seems to be my "Notifications" (apps settings) and the other seems to be "Ringtones"(phone's information). I've never seen this before. Usually the sounds are the same, aren't they?
Any explanation or information is welcome. The app's developer had never seen that either. Rebooting the phone doesn't help.
Thanks in advance.

I'm using Pimlical. It started out as Datebk many years ago and I've stayed with the developer ever since. I beta test it also but have never seen anything like this. I've made sure the sounds I use are in both lists. Hopefully that will stop the screw ups. The developer has the Pixel 6 Pro also and his doesn't have this issue.
