Slicing Trouble in Cura 4.12

[Kevruns2 0]

Cura has been giving me some trouble and I'm sure it's an easy fix but I just can't seem to find my issue on past discussions. That or I'm just not sure what to call this issue since I'm pretty new to 3D printing but anyways, here is my issue:

 

Cura is slicing my first layer into 3 different sections and then begins the second layer on top of that first layer and some of it gets printed in air which results in poor bed adhesion and a failed print. Does anyone know how fix this issue ? Any help is appreciated.

 

Also, I've debated whether it is my bed-leveling but the skirt prints well.

Post the STL file.  From here it looks like the bottom isn't flat on the Cura build plate.
