"undefined Attachment" message when importing items

I'm getting an "undefined Attachment" message (see screenshot) when importing items from my library's catalog using both the Firefox and Chrome connectors (version 5.0.195, Zotero version is 8.0.4). The message is only displayed for items 2-10, not the first one. The debug ID is D1210265728.

Is this a public catalog and can you link to it? I don't think I've ever seen this and I suspect it's because the site is serving some weird metadata

Yes, it's a public catalog, here's a link: https://rds-tue.ibs-bw.de/opac/RDSIndex/Search?lookfor=test&lng=en

Thanks -- yeah, it's the COinS metadata on the page. I need to look more closely to say more, but that's definitely what's causing the weird import. It might be possible to write dedicated support for the library catalog/discovery layer; it's an odd system that I haven't seen otherwise.
