Not able to view the entire letter when accessing alternate characters

I am not able to view the entire letter/word when trying to access the alternate characters on Laura Worthington fonts.  When I highlight the letter/word part of it goes out of view.  

It is particularly hard to view letters like y that have descenders.

In this case I am using the font Samantha Pro Upright

I belong to a craft group, and I am not the only one experiencing this issue with Laura Worthington fonts.  My other OTF fonts work fine.

The first image shows what the word looks like after typing it in.  The second shows after highlighting and using the arrow to access the alternate characters.

Thanks for any input.
