Ultimaker Cura 5.1 - Software slices layers in empty spaces

[jetfire158 0]

Hi I am having a problem with Cura slicing extra layers in spaces where aren't supposed to be any:

The other spaces are fine. Could it a problem with the model? I am not sure how to fix it. Any help is appreciated.

Oh wow, nice! Thanks. 

 

Could you tell me step by step what you did using Mesh Tools to fix the model? I tried clicking 'fix model normals' on the original file but that didn't seem to do anything.
