Hi, I'm using Debian subsystem for Windows 11 and whenever I export a BIB callnumber batch of spine labels to PDF, all the data is rendering incorrectly. The template that I set up is working fine, and ONE of the labels comes out correctly, but all the other call numbers are running together and even going off the template. I tried recollecting a new batch using the same books, but it didn't change anything. Also, whenever I try exporting a selection of the batch instead of the whole thing, I get an "error 500" message. Happy to give more info if needed, but I'm not sure what else I can say. Couldn't find any reason for only one book to formatted correctly and all the others come out all piled up. Hope this all makes sense, and thanks for your time!
The callnumbers running into each other could be an issue with your template settings. There are also currently some other open bugs about label printing, like bug 29994. Maybe you could check if it relates to your issue?
Maybe give us the settings for the layout and template you are using and the resulting pdf file? I think it would help recreate the problem if we have the exact measurements and everything. If the callnumbers are running off, it might be to do with callnumber splitting? Depending on the classification source, the splitting rule might not be splitting like you would think.
We don't have enough information here to move forward. Please reopen with information on how you set up the label printing and some sample callnumbers.
