Prefab Pivot Causing Problems for Instantiation

There is a platform, which is what you control, and the ball rolls on it. Very simple. The ball also collects grapes. But, for some reason, the grapes are messed up. I have tried fixing it, creating new prefabs, etc. But the problem is this: I need to instantiate grapes, and bc of this wrong pivot they spawn in the wildest places. ON TOP OF THAT, since I started unity with this project, and this project is my graduation project, as a newbie, I didn't use empty game objects to not warp objects physically when parent/child, my bad. So that is included in this clusterduck, which doesn't work even when I instantiate as a child of the platform and just stays a weird flat purple, so to not have that I need this pivot thing fixed for the actual grape.

What is this?? Nvm those empty game objects in the hierarchy, I thought I found a fix but turns out you can't delete parents in prefab. It's my bad. I don't even understand what's going on here. I reset transforms, I tried different things but no, it gets worse everytime. Does anyone know how I can fix this pivot issue? I couldn't find anything useful and I'd really appreciate it. I don't even fully understand what's going on in that screenshot.
