I get this error when trying to import an xlf file: Imported XML cannot validate with the schema: The 'al-object-target' attribute is not declared.

LogTrade Connect.g.zip
BC15.0.35903.0-se
al-4.0.170493.vsix
I would really appriciate if you could prioritize this since it's a blocker for the BC15 version of our app.
Thanks!
