I have a PDF Writer which generates PDFs with 4 layers:

Frame, Basemap, OldLine, NewLine.

NewLine is an interactive layer (hover over it to see attribute details).

I would like to also do the same with OldLine - which has a gap that NewLine fills nicely. However when I make them both interactive then, in the resulting PDF, I either get to see just the first part of oldLine or the whole of Newline...

Both lines are visible in the sidebar bookmark and the mouse pointer changes when I hover over the invisible linework.

I have tried various layer orders (guidance says interactive are always at the top anyway) and many other settings, but can't get a decent output with both layers fully visible and interactive.

Is there a hard restriction to one interactive layer?

Cheers
