Output text in "owner" line not standardised

Hi.

I have the free Starbox.

In the output on the post, there is a difference in font size for the word “at”, where it is larger and sits lower than the rest of the text on the line. All the text on that line should be the same size and sit level.
Please see this image:

My theme settings are:
Name size: 18px
Description size: default

How can that be fixed by me?
Otherwise it will need to be something you fix in your code.
