Application menu popup varies with window decorations

Hi, I’ve installed multiple window decorations using pamac, since KDE store (Get new window decorations) has always been buggy for me. Two of these are lightly & materia. I’m currently using lightly with materia-dark global theme. Here are the info for those two packages:

Here’s my KDE Plasma info:
KDE Plasma Version: 5.21.5
KDE Frameworks Version: 5.82.0
Qt Version: 5.15.2

And here’s my problem:
Issue: Application menu pops up somewhat away from application menu
Observed result: Application menu pops up somewhat away from application menu icon when I’m using materia-dark global theme with materia-dark window decorations. The distance is shown using a green line, which is absent in the 2nd pic.

Expected result: However, it pops just under the icon when I’m using materia-dark global theme with lightly window decorations. I want that to happen in materia-dark aurorae theme too.

What I’ve tried: Searching the internet gave me things like aurorae themes and kde plasma global menu, which do not solve my problem.
I hope my question is clear, English is not my 1st language. Thanks in advance.
