Corrupted data in multiple-choice value-relation attributes

Hi all,

Since a few weeks i noticed a repeating error when using a value-relation setup with multiple choice. When adding point-geometries where a few different attributes are setup as multiple-choice value-relations, the selected choices change directly after saving the geometry. For example one of the attributes has 10 different values to chose from. When selecting 2 of them and saving the geometry, if reopend, the values i selected changed into 7 different values.

Been struggling to find the bug/error, any help is appreciated!

@SenneSchodts27 , can you share a sample project?
