Is there some place where the bug types of iPad Analytics meanings are listed ?

No.

analytics t are not human readable, they are meant to be read with a software interpreter.

If you aren’t a software engineer or developer, which apparently you aren’t, there is no reason for you to be looking at them.

Curiosity is great. Unfortunately, we've seen way too many people fall down the rabbit hole that is trying to understand analytics.It just tends to cause a lot of needless anxiety and frustration. A fair number come to the conclusion that every device they own is hacked (they aren't). So, I tend to recommend against it.

Rather than try to parse what, to normal humans like us, is meaningless gibberish, you might get further by explaining exactly what problems you're having with your iPad.
