Hi @sonicfroots,
so you see already minified CSS/JS files in the Design-Manager? Normally you don’t need to minify CSS/JS files in the Design-Manager since HubSpot will do that for you “on page load”. If the files are already minified it’s most likely because they were uploaded/pasted minified.
If you go back to the first/second revision(just looking, not restoring) of the file - is it miniied already? If so, then it was like so from beginning.
If you want/need a unminified version of your file you can use something like https://www.unminify2.com/
hope this helps
best,
Anton
