Why isn't my model's skeleton not working?

Hello, I am fairly new to Unreal and I am currently working on a game. I imported a model that I made in Blender and I even rigged it myself, but when I brought it into Unreal it started to go crazy.

I discovered the issue had something to do the its IK bones, so as a test run I removed them to find my model rag doll like it was supposed to, but the limbs where the IK bones connected to disconnect from the body.

I tried a few other options but none of them seemed to work either. Is there anyway I can get my model into Unreal with a working skeleton using Blender or the engine itself?

I was going to give you my skeletal mesh instructions but they would not fit.
