Comment:

 @metalandcoffee I know that these are editors within custom metaboxes, but
 can you clarify whether the Classic Editor plugin is active? I'm not sure
 that would make a difference, but confirming the behavior with and without
 the plugin could help find the issue here.

 Just to be sure, I double checked there were no TinyMCE updates available.
 4.9.11 is the latest 4.x version and there are no 4.x
 [https://github.com/tinymce/tinymce/compare/4.9.11...4.x bug fixes waiting
 to be released].
