why officeR's microsoft word disconfigure out of nothing?

Hi.
It's a rare issue. I have my app in shinyapps and it uses officeR to generate a document that contains some flextable. I published a version weeks ago and everything was fine. Until yesterday, some tables just disconfigured, wrong sizes beyond page width. In some other non shiny program, it happened something similar, a disconfiguration out of nothing.

I'm wondering about the reason for this since in our side there was no update of any nature.

someone had a similar issue?
