How can I fix the formatting issue with the separating line in modelsummary output tables?

Question

When I summarize my regression outputs in a modelsummary table, I get an unpleasant formatting problem.

I used the following code:

modelsummary(ols, statistic = "p.value")

and get the following output when I knit it to PDF.

Output after knitting to PDF

The separating line has these colons and is not nicely formatted.

Does anyone know a way to fix this issue. Many thanks.
