That seems to be (at least in parts) an issue with the data, especially the empty value of the @level attribute on <title>.
In my (short) tests the @level attribute was always set correctly to "m" for a book.
@KristinaRichts can you tell me how you added this <bibl>?

I just recreated the entry again as a test entry. The title is now displayed (See screenshot), and also the "vol" specification, but "vol." should not be displayed. It seems that something went wrong with the title input field. You can see that on the screenshot I took earlier. "Monograph" and "Series" is missing there.

It's a bit confusing, that the evidences are listed one after the other (see screenshot), especially when there is no author and the evidence begins with a ":"

3. test entry:

@AnastasiaWawilow and I just had a look:

1. Regarding the initial issue with the missing title. We could only reproduce this when we (manually) entered an <mei:title> without a @level attribute. This should not happen with the MerMEID editor, so this has already been fixed?
2. Regarding "'vol.' should not be displayed.": You can suppress the output of "vol." when you click "clear unit".
3. Regarding "evidences are listed one after the other": This is addressed in 5aeb5a3
4. Regarding the leading ":" for empty authors: This is addressed in 6070a4e
