I am finding an issue that seems to be related to Toolset Blocks, on WP 6.7.
10 second video: hidden link
This behavior only began happening after updating to WP 6.7, and only on sites that have Toolset Blocks enabled. If I disable the Blocks plugin, the row of buttons including Save appears in the correct position, above the sidebar. But when the Blocks plugin is enabled, the row of buttons falls behind the sidebar when it is opened.
I have recreated the same behavior on multiple Toolset Blocks sites that have been upgraded to WP 6.7, but do not experience it on any of my sites that do not have Toolset. The site I've linked is just one of many experiencing this issue.
*** Please make a FULL BACKUP of your database and website.***
Can you please update All Toolset plugins to it's latest official version and I hope this will resolve your issues.
