Product Options Modifier not showing correct price (if mod is above 1000)

Hi all, I have an unusual problem with some of our global options that have a +1300 modifier. If any of our modifiers are over $1000 then it removes the thousand part of the modifier and shows incorrect pricing. For example, if the modifier is +1300 then on the front end it shows just $300 and not $1300.

Anyone run into this before or have an idea whats going on?
