The problem was occuring on the Cayin device itself and not my PC. Unfortunately, I have not been able to reproduce this issue again so I won't be able to help any further. If I come across it again I'll try and see if I can reproduce it.
This is another issue I wanted to bring up to you that I can reproduce. When I'm searching for an artist by name using the library search feature, I notice that an artist starting with the string "." causes inaccurate search results when searching for a specific letter. To explain this in more detail, I have an artist named ".sinh" and whenever I search under the letter "s" I'm getting results from the start of the library instead of all of my "S" named artists. (See the following screenshot) I haven't noticed this happening with any other letter except S.I've already created a video of myself reproducing this. If you need me to email this information to the email address you mentioned to me earlier I can do that as well.
This is the start of my artist list before enabling the library search option:
And this is what it looks like after searching for the letter "s".
