Odd label problem

Got an odd label problem on Sierra. High Sierra to Catalina are fine. When the app is opened then the labels look like the top part of the screenshot. When I change the window size then everything is back to normal.

The labels on the right side are the same as the labels on the left side. I have tried to change the window size when opening. But that didn’t change anything. The labels are simple labels so I don’t do much anything with them except load some data from a database.

Do they all have the same multiline setting?

Yes, all 8 labels have multiline off.

I remember, I had that problem once, I think it has something to do with alignment of this labels inside the object …
