Hello! What happened: in a template I created some new paragraph styles in order to change an entire document by loading the styles. The main style for flow text in the old document and the new template is called "Flow text", so it's overwritten when loading. The new style's settings are the same as the old, except for the font and height. Then I loaded all the styles into the old document and found anchored objects not working anymore. See video.
At first you see the old document where I can place an object in line with text which is shifting the text down and I can adjust the postion. In the new document with the new style this doesn't work anymore.
At first I thought this would be Indesign version related, because the old was made in CC2019 and the new in CC2022, but when I export an IDML from 2022 and open it in 2019, the behavior remains.
I also compared all general settings of ID and also the anchored object setting to be the same.
Addition: I also played a little with text wrapping options. The only setting which brings sort of the same result is "Jump object", but that's not applied in the old document. I suppose the solution is so simple, I just don't see it.
