Font size changes at random in tables on Apple Notes app

Hello,

I am having trouble with font sizes when I use tables in the Apple Notes app.

When I create a new table, the text in the table uses the default 'System Font Regular 12.0'. But then the text in some cells in the table mysteriously changes to size 10.3 (I think still in the same font). As far as I can see, the only way to get it back to the original size is to select the text in each individual cell that has been affected separately and change the size back to 12, which is a bit of a pain in a large document with many different cells (if I select all the cells in the table, it doesn't allow me to change the font settings - I have to highlight the text in individual cells directly).

So, my question is:

(1) Is there a way of preventing notes from changing the text in random cells to a different size?

(2) If not, is there a way of getting all the font in a given table to go back to the default size rather than selecting the text in each cell individually?

Thanks
