Seems like that when clicking on empty space it does not respond. Try to double click a text in this line (like the callsign itself or the time band text). LMK if it works. if it does - I will know for sure it is the problem. I was able to duplicate it but want to be sure.
can you please make a video with your phone ? I want to see exactly what you double click.
Also check it is not an old CQ as there is popup telling you this and it may hide somewhere behind another window.
I was not able to duplicate so I need your assistance.
I just did the install yesterday and have the same problem
