Problem with scaling and moving models

[Qapandt (Arch)]

I’ve recently downloaded some models from sketchfab and decided to import them in Roblox Studio. Firstly I tried to edit the ammo and give it texture and then I noticed something is wrong. When I tried to make it bigger via scale property the origin of the scale was put somewhere else.

Here’s an example:

What could be the issue?

Please can someone help me, I really wanted to work on making a gun but this problem grows other problems, please can someone help me? Any help will be appreciated!

Oh nevermind, I used the Import 3D tab which messed up everything, turns out all I had to do was to insert a meshPart and browse through my files and import the 3D model.
