Editors-XTD button in pro version

When toggling out to code view and then back to editor view - no other changes - Sourcerer code is breaking. I'm sure this is interference from JCE Pro, as Regular Labs' xtd buttons don't appear either. Will the pro version fix this and allow me to lock the code from such interference? I am expecting the security features will allow me to lock out other back end editors from modifying the code, based on your documentation.

J 4.4.9
PHP 8.3
JCE Pro 2.9.82 (latest as of this date - just opened a ticket there)
