Lightroom Classic import from another catelogue imports as read only and I can't change

My workflow is generally edit on laptop

export as a catelogue

import to desktop Lightroom

then I have to move my photos to the right location because of the silly folder import regulations on the exported catelogue

However, of late all my exported catelogues have been imported as read only and I can't then move them.

I managed to solve this once before, god knows how, but its got to the point where I am dreading doing this because it took me HOURS to solve.

I think I had to go through every folder and every file to untick read only. Its utter hell.

Anyone know why this is happening, how i fix it for my imported photos and how I stop it happening in future, its nuts, utter nuts.
