I searched the forums but the only solution I came upon was to convert the object to a smart object and then scale it, hoever doing that stops my blend modes from working correctly. Any help is appreciated, thanks!
If there is a Smart Filter mask involved that is not all white you may need to scale of the mask to match the smart object scaling you changed. The filter mask would have been created for the prior object scaling. Filter are not scaled however they can be masked. All smart filters on a smart object layer share a single filter mask. Here you can clearly see the smart filter mask did not scale when I changed the smart object layer scaling.
However I was able to scale the Filter mask to match.
