Edit wdg not loading select column current value

[dankitchen]

In Tactic 4.8.0.v01 (I hve also tried 4.7 and 4.5) when right-clicking in a table with related styles (ie product with product category) the select wdg in the edit form loads with the current value not selected (just has the "-Select-".  Technically users can edit in the table directly (which does work) but it has caused issues with users who use the edit form to edit data which then clears out the related selection if they don't set it again.  The error seems to be in the labels_expr as the default values expression for the category_code edit field works fine

Thanks!
