### Steps to reproduce

1. Have a custom field of type Version (e.g. **Fix Version**), mark it global (For all projects), doesn't matter whether it's multi-select or not.

2. Go to My page and open WP table configuration for any Work package table (add one as necessary)

3. Begin of the insertionAlternatively, go to the global work package view

4. End of the insertion Choose Filters tab

Begin of the insertion5.End of the insertion Begin of the deletion 4.End of the deletion Try to add the custom field - it's not in the dropdown


### What is the buggy behavior?

* Global version custom fields are not available for filtering. They are available for Columns, but not for Filter.


### What is the expected behavior?

* Global version custom fields should be offered for filters, just like other types of CFs (those work fine).


### Screenshots and other files

Config for two CFs of different type:

In Columns configuration for WP table, both work fine:
