Cannot edit headings?

When I use any heading after the latest update, I cannot edit them. This goes for new and existing headings H2 H3 H4 H5 Etc, I have tried saving, quitting but it seems the cursor does not want to go in edit mode on any of my headings

Anybody else having this problem?

I have the same problem

Where are you trying to change them?

I use the project settings dialogue where there is a pull-down to select each level of heading separately. This is working correctly here in v2.5.2. An easy route to it is by clicking the little ‘sliders’ icon next to the project title in the window’s title bar.
