Filter Col Selector() does not create right-click formulas

[#1]

I have an add-in that has a 'Filter Col Selector'.

Yet, new formula columns don't appear when I try to create quick calculations by using right-click actions. 

The issue seems related to the following post, although new formulas columns created directly in the table do appear in the Filter Col Selector.

I am sorry that you have not had a response to your question yet. It might help if you provide some more context and explanation. If you can share an example data table with saved script that really helps. Or at least some screenshots to illustrate your question.

I re-made the elements in the GUI and got it working. Not sure what was the issue but this time it works as expected.
