The problem starts when adding a version filter on 14.0

**How to reproduce (rough sketch)**

*   Create two projects A, B
*   Create a work package with two custom fields that are active only in A
    *   One of them a list custom field
    *   The other one a text custom field
*   Assign custom values for those two fields
*   Move the work package to project B, where neither of the fields is active
*   Add a baseline comparison to it that includes the move of the project
