Description:
Dear Libre Office,

I am having a text formatting issue that seems to be in Libre Office 6.4.4.2 and wondering if you could help.

When LO is reading a Word document, square characters are appearing where a line break should be. However, this is inconsistent, as the squares only appear sometimes, not at all line breaks. And it's only appearing when the doc is opened again in Word after being saved in LO. The only clue we have is that it is only happening when letters have been written vertically on the page (a vertical poem, see below) in a Word doc. 

V
E
R
T
I
C
A
L 

Please let me know if you have any idea what is happening! I'd be happy to send you the documents in question.

Sincerely,
Rose Michel

2.LO does not see any strange square marks and the doc is saved in LO.

Actual Results:
