Identical characters displaying very differently in adjacent spreadsheet cells

Running LO v 6.4.4.2 on Manjaro KDE. I find this puzzling behavior where the same identical character displays quite differently in different cells of the same spreadsheet. What can possibly be the reason for this?

Thanks

Please provide a sample file.

In preparing a sample file, I realized the problem stems from conditional formatting.

Sorry for wasting your time.
