Importing animations from Blender results in multiple skeletons and animations

When importing a simple animation from Blender, instead of the single animation I am looking for, 1200 import instead. I am using Blender version 2.78, and UE4 4.21. An animation using the same settings (but a different animation) worked in previous versions.

I followed the guide from this guide exactly to no avail.

Can anyone help me?

Thanks in advance!

Resolved; for anyone wondering, I did not export with proper size set in Blender.
