Motion Blur and Smearing on Assets In Motion

I have 2 issues happening here that I am hoping someone can help me.

One issue is with geometry collections. In the video linked here, I have some assets that turn into geometry collections. When the geometry collection fragments move around there is a ton of motion blur. It looks like streaking across the screen. I have motion blur disabled in project settings and I cannot figure out why this is happening.

The second issue is with the hammer swinging in the video. You can see there is ghosting or smearing when the hammer moves in front of objects. This only happens in indirect lighting inside of buildings with no direct light sources. I am using TSR and Lumen. Turning Lumen off fixes this, but the game looks much worse without it. Moving to a different AA helps, but doesn’t totally fix it.

If anyone knows why either of these issues are occurring or has any insight I would greatly appreciate it.
