For everyone who encounters the same problem. Do not panic! This bug is not a WP-Smush bug. That Is somehow related to javascript. If you have WP-Rocket installed uncheck the option
Combine JavaScript Files
under DASHBOARD/CACHE/FILE OPTIMIZATION directory. Image sample
Ok, false Alarm guys. It wasn’t even a Smush failure. Wp Rocket conflict. Wtf I was pissed of, and I canceled the trial.
