Incorrect issue detection

I am having a very weird issue with imported RIS files. For studies with no assigned issue, rather than keeping it blank, Zotero is completing this field with the author's email and location. The attached image is from an imported RIS file taken from Embase. This is not happening with other reference managers and although I just updated Zotero to the latest available version the problem persists. Any ideas why this is happening? Thanks

We'd need to see the RIS that causes this. Post an example entry here or to pastebin.com and link to it.

I am pasting the first part of that reference directly taken from the RIS file. It seems like Zotero is using the first "M1 - " line to populate the issue section.

In contrast, for other references which include an explicit "IS -" line, this is the value used for the issue field, as expected, such as the value "18" in the following example (from the same RIS file):

The behavior is systematic. The RIS file contains a few references that do not include the "IS -" line and in all cases Zotero is using the first "IM -" line as Issue. This happens with different RIS files and since the error happens during the import process it affects any citation style that I use later.

In case it is relevant, I am currently importing the RIS files using:
File -> Import... -> A file (BibTeX, RIS...)

Hope this helps, thank you!
