If combo box is setup to cell in merged cell group it doesn’t show the drop down Arrow.
Also once you have selected a value for the drop down it displays the numeric value instead of the test display.
To reproduce Load Attached Test app
Click Button1 on bottom left.
Then set dropdown in Cell E3
Then set dropdown in Cell F#

Thanks for the sample project with template file.
After an initial test, I observed the issue as you mentioned by importing your template file (e.g t1.xlsx file) into GridDesktop. I found Combo control does not work correctly in the merged cells in GridDesktop. If combo box is setup to cell in merged cell group it doesn’t show the drop down contents fine.
