Meshmixer to Cura Slicing problems

[Lemmywinks21 0]

Hoping someone can help.  I am trying to build an iron man suit and I am having issues when I cut the chest plate in meshmixer and import it into cura.  So far, I have not had issues with cutting objects into smaller pieces, but I am getting a weird line on my prints almost as if it creates a support line inbetween a part that is not supposed to be cut (picture below).  Hoping someone can help me.  I can't seem to figure out why it's only doing it on this 1 STL file. Thank you in advance!

I figured this out.  Carry on!
