Unwanted Large font when copying from one worksheet to another

I have tried everything I can think of to fix the following problem.
When I copy from one sheet with a font size of 11 to another workbook the font size increases to 20.
I had a while ago increased the font for the formula bar to 20 but since I have changed it back to size 11.
When I open both worksheets they show size 11 but when I copy some of the data to the other worksheet
it changes that back to size 20.
Any ideas how I can fix this ?

I wonder if a Cell Style is being carried over.  On fresh sheet, try copy, then Paste Formulas.  This prevents styles from carrying over. Try that.

Copying to a new sheet the format is correct.

When copy from source to old sheet, try again Paste Formulas to avoid the style.

If you still get the large font, check in Cell Styles in the Excel Ribbon.

I copied all the cells containing formulas to a new worksheet as per your suggestion
and it worked fine. The data now being copied is correct size.
I can only conclude it was the destination sheet containing that data range that was formatted.
