In Character Style for text there is a bug that does not allow for manual setting of height between height of an paragraph. Only presets cand be used. Image with highlight in red and a short screen recording of proof.https://youtu.be/VNQTQZFwoUE
I have this problem, too. More details: it only happens to me after I resize text with a transformation (Ctrl + T). Then the bug presents itself.
Weirdly, when this bug is happening, I can adjust the line-height via the Properties panel, but if I make changes via Properties, it's the Character panel that shows the proper line height, while the Properties panel shows the wrong number.
