Envelope does not print both 'from' and 'to' addresses

 LibreOffice Version: 6.3.5.2 (x64)
Win7 -64

Operation:
> insert->Envelope->Envelope

After setting the ‘from’ and ‘to’ addresses:
> Insert

On the ‘Envelope’ moving either the ‘from’ or the ‘to’ address frame handles will cause the other address to no longer be printable although it still appears in the writer. The only ‘solution’ that seems to work is print the envelope twice. The first time with the address visible to be printed, the second time by deleting the address just printed and printing the other address. This behavior is different from previous versions of LibreOffice.

The same behavior occurs with any change within the respective frames. That is, if I add an Attention line by inserting blank pages into the ‘from’ frame, the ‘to’ address no longer prints. If I change anything in the ‘to’ frame then the ‘from’ address no longer prints. Further, if I add blank lines outside of the frames, to, for example, add an attention line, then the ‘to’ address no longer prints.

I might also add that the behavior seems to be erratic, in that I just checked all of the above and when I viewed the output in the print preview window, the window showed all of the envelope. So I don’t know what to say. One day ago it worked as above. Today it works as expected.

It is very problematic to want to understand mistakes that no longer exist.
