Testing and Development is aware of this issue. There is currently no Work Around for getting the Edit.. or Other... lines to show on FileMaker Go 14.0.3. The only way to get the last item to show is to have an additional "Blank" value at the end. I will add this post to the current report. I will respond with any new information.
If your solution wouldn't be broken by the use of new features, FileMaker Go 13 does not have this issue.
Thank you so far, we will limit it to Go 13.
This issue has been addressed in FileMaker Go 14.0.4.
