Import World Settings not working anymore.

Hi,

I've noticed an issue with the import settings for making new worlds. When ever I export worldgen settings and try to import them into a new world I keep getting the error in the attached image. 

 

I haven't edited the file in anyway and have tried multiple exports and none work. 

 

I enjoy messing with custom wolrldgen dimensions using these files, and I'm hoping for a fix in the near future. 

 

Thank you for your time.
