Module Icons not saving with the template

actually, I spoke too soon.
After doing a few other changes to the template (re-enabled parallax, changed background image for one wrapper), SOME of the icons are now gone.
a few still remain.

Cleared browser cache, saved template etc and they are still gone.

it comes when editing the wrapper CSS, can you confirm ?

it was happening when editing the block css
Even if I don't validate and simply cancel the editing, the icon has gone

please replace this file in the assets folder of the component

clear the browser cache and tell me if it works

works perfectly

Now you just need to fix module titles not storing the correct alignment if they are copied from one module to another

ok cool for the icons
can you explain me the problem with the modules ?
