Trying to print a 3D turbine engine. My issue is that once importing certain items into Cura, the first bottom "support" layer (provided by designer) shows as gray in cura and doesn't print. Its like the object is sunk into the glass and is omitting the very first layer. This only is happening on certain parts and I am not sure how to fix it.
When looking at the solid view, you can see that the support is clearly underneath the fans. However, when bringing it into the first layer view, it is completely omitted. Side fact, when looking underneath, the first layer is red. Not sure if this has anything to do with it.
Item I am printing: https://www.thingiverse.com/thing:1327093
Example part that doesn't want to print correctly: LPT_Stage_1_Stator_With_Supports.stl
Screenshots of what I am seeing:

Thanks for anyone who is willing to help!
