Actually kdepim-apps-libs should be removed, it stays on 20.08 but instead it's marked as depend on grantlee-editor which isn't correct. Rebuild grantlee-editor without kdepim-apps-libs as depend so it can be safety removed.

Thanks for reporting, kdepim-apps-libs is already removed from the repo, I did rebuild all that used to require it, grantlee-editor included, but failed to actually remove the depend.....

EDIT:
Rebuild is up, you can try it now with:

sudo pacman -U https://repo.kaosx.us/build/grantlee-editor-20.12.0-2-x86_64.pkg.tar.zst
