Phone Numbers Disappear!

I am experiencing the same issue with some disappearing phone numbers, and some text is being scrambled not sure if these the same or separate issues. Even stranger, I partnered with a colleague at a different company who said that it looked fine on his end.  Mostly it comes up wonky but at least 1 time I reviewed it came up okay for the same project.  Myself and the colleague who assisted are both using MS edge and Windows 11. I do not have access to private browsers per my company's policy.
