Erratic / unexpected leading despite using text styles

[PeeGeeBee]

Sorry to come back to this general question again. I'm attempting to revise a simple Affinity Publisher project from a few months back and encounter an annoying problem I just cannot figure out. When I add new text to a document, using either the Place feature or typing directly into it, I'm getting a huge discrepancy in the amount of leading showing, even when I use the same text style I've used for the earlier part of the text, which is being displayed as I wish. I've selected some of the original text, and updated the textstyle then applied it to the new text, but still the extra leading is being added. I've checked the character panel and can't see anything there that might be affecting it. I've gone through multiple tutorials and can't see where the solution lies, or what the issue is.  Any ideas where I should be looking. I'd have thought selecting No Style, to remove all styling, then applying my chosen style would do the trick, but there's clearly other forces at work! Thanks

Is this the baseline grid problem that I had trouble with?

@PeeGeeBee These are just off the top of my head;

Really we would need to see a Document which exhibits this behaviour as there could be multiple causes which are contributing to the problem.

What sort of Leading do you have set for the Paragraph Style? There are a number of different ways to set it. I like to use Exactly.

Then there is the question from KarinC about the Baseline Grid, note that the Baseline Grid can be set to Off, Inherited, and On in the Paragraph Style. The Text Frame can also have an independent Baseline Grid set and that may be set to a larger value than the document Baseline Grid.

Finally there is the Leading override which is set at the Character Level.Your Default [No Style] Paragraph and Character Styles could be contributing to this.

You may have overridden something in your original document which is showing what you term as "correct" leading so when you place / type the new text using the same Paragraph Style you are seeing the actual leading you have set.
