Front end postid-css.css and postid-js.js are don't update/get generated

I’m having a weird issue on an AWS lightsail WP site - not sure if the bitnami lightsail is related.

The issue behavior is that editing content in the editor generates and updates the -draft.css and .js files correctly.

However the frontend versions without the “-draft” don’t get updated after clicking Done and Publish repeatedly.

I tired clearing the cache, don’t have any caching or optimization plugins and on other servers, the same site doesn’t have this problem at all.

What could be the issue? Any ideas? I’m out of things to try!
