Spaces between words randomize when pasting text from Open Office

I am the main records keeper for our campaign and write up the session after it is complete. I do this in Open Office, and it usually comes out to between four and six pages.

Sometimes, about one in three pastes, the spacing between the words randomizes some words get scrunched together. Usually (about two thirds of the time) this does not happen, and it doesn't happen if I send the document to someone else and they copy/paste it.

The formatting is quite basic - nothing interesting - and I am using the current edition of Chrome on a Windows 10 machine.

Has anyone else seen this?
