Styles not updating font size

When redefining a style for which the font size was changed (and, of course, that style having the font size setting checked in the its config), the update of the style throughout the project doesn’t apply the font size change.

[EDIT] Experimenting: as a matter of fact, nothing font related seems to work. Font family, font size. (My style is Paragraph formatting. I am pretty sure this used to work when the two font related options are checked in the config for a style.) (?)

I bounce my paragraph to a different style and back, and it is as it should afterwards. Something is just not happening when redefining the style. (In the subsequent project/style update phase, that is.)
