Music goes away when I pause?

Hi, I have an iPhone 11, and when I pause the music, it disappears. (Sometimes it disappears after 5 seconds, sometimes after 2 minutes) So it disappears from the control center when I pause it. It's really annoying because I have to keep turning it back on.

This is what it looks like when it's there:

and when it disappears

This minus sign is really annoying me. Is there anything I can do about it? (I can't explain it very well)

thank you for your help
