Exporting values of "angle between two lines" (Q3DC) doesn't work

Operating system:
Slicer version: 5.0
Expected behavior: Exporting values of “angle between two lines” (Q3DC)
Actual behavior: Hello. Hope you are fine.
Two weeks ago I did export the values that I found by calculating the angles between the lines on Q3DC tool - it worked normally, creating a doc named “angle” with the measures. Now I’m trying to do exatcly the same process, but when I click the “export” buttom - after choosing the directory - nothing happens. I’ve tried several times, with no success. Can anyone picture anything I must be doing wrong that explains this?
