duplicate entry fails with "you don't have edit permission"

Hi,
i have some entries that are linked to two folders, on one folder i have full access, on the other folder i have only read access.
When i try to duplicate an entry i edit the folder in the "add copy" form, select only the folder i have write access to and try to save that new entry, but then i get the "you don't have permission" error
i can create new entries in that folder without error.
why does the copied entry check the permission of the source entry?

#edit 1#
copying the entry with an user that has full access to both folders works

#edit 2#
the problem only happens with RDM 2026.1.15, using the web interface of Devolution Server 2026.1.12 works
