What does this R symbol mean?

I uploaded text to the fourth column for a topic model, but instead of text, this symbol is showing. When I hover over it, I can read the text; however, I want to make sure this symbol won't misguide my structural topic model analysis.

Thank you!

I just ran the topic model without issue. I think this symbol suggests that the cell contains a large text (e.g., pages of words). Thank you all for your help!
