Vizlib Table V3.19.1 Actions issue

I have added 2 actions in a Vizlib Table column action and the order is as below:

Set Variable

Selection in Field.

 And when doing the testing I also display the variable value to make sure the selection in field is correct. and I noticed that I am not getting the result I would have expected.

My expectation is that by clicking the column first I update the variable value to say "A" then I can confirm this action by seeing the display of the "A" in my textbox. and I should be expecting the field value be changed to "A" as well. but the second expectation did not come true as it still display the previous value. and when I click the column again to change the variable value to "B" then the selection in field is updated to "A" instead of "B". seems like there is a delay in the selection in field action.

Has anyone experienced the same or did I miss anything? thanks
