font size displayed wrong

Hi,

generating a score and adding some hints via staff text (strg + T) or lyrics ( strg + L ) to indicate the way I want it to be played, some oddities occured.

By overseeing the final and exported result a friend of me reminded me on a piece of text differing in its font size while it should be as small as the other indices.

It was obviously true. The "Sax." staff text, ( marking cue notes ) looks smaller than the staff text one bar further.

Now the oddities:

If i double click both text pieces, entering the editing mode the bottom task line shows me "font size 8" in both cases. So my thought: some kind of visual trick.

But no. Infact the size differs but I have no tool that can show me the current size.

If I right click and enter the editing mode it says the current font size was 11 ( ?! Oo )

So. I copied the larger font size 8 text and pasted it into the field of the smaller one.
It was larger and by marking the letters it shows me "font size 9" ( ?! Oo meant to have copied font size 8 )

If I mark both words together in one field and change the font size it changes normaly.

The problem is: how do I get the true information about a current font size? I dont want to adjust a smaller looking font size 8 to 9 just to be as large as a font size 8 from elsewhere.
It should be 8 and 9 or 7 and 8 not 8 and 8 differing obviously.

Don´t know if someone gets me. I´ll upload the "corpus delicti"

( page 2 Letter E "Sax." ( looking smaller beeing font size 8 ) ... last bar first line "Echo" ( looking larger beeing font size 8 aswell )
both text ar staff text.
