Hey there trwhite6878,
How are you doing today?
First of all thanks for taking time to write a review and rate WP Smush, we appreciate that ??
With regards to your issue I don’t see that you have any support tickets so if you’d like us to help you troubleshoot this further please open a support thread on WP Smush forum here or in case you’re using premium version of the plugin you can open a thread here.
With that said default lossless compression shouldn’t be any quality loss, Lossy (that is available in premium version of the plugin with Super Smush) can sometimes cause loss in quality but it can be barely visible.
Either way if you’d like us to further investigate that please open a thread and we’ll be happy to help ??
Cheers,
Bojan
