I generated a gcode from your project and everything looks good. The "Z" has an Initial Layer Height of 0.30 and after that it indexes 0.20 every layer.
The Flash Forge slicer "Flash Print" does not use "G0" for travel movement. I have no idea if that is because Flash Forge firmware doesn't understand "G0". The "Industry Convention" is to use "G0" for travel moves and "G1" for extrusions and that's the way Cura does it. The printer may be having trouble with lines like this:
G0 F600 X-26.674 Y0.39 Z2.5
A "G0" travel move like that will occur before every layer change but that starts right from the get-go in Layer:0. I have no idea why your printer would start ignoring them at a higher Z and I haven't seen any bug reports regarding behavior like that.
You can do a test by enabling an instance of the Search And Replace post-processor.
Search = G0
Replace = G1
Use Regular Expressions = False
Other than that I don't know what to tell you. The Cura gcode is correct.

Without knowing your printer and settings we can't tell.
With the model loaded and Cura set up to slice, use the "File Save Project" command and post the 3mf file here.
Post a "bad gcode" file and that Simplify3D gcode as well. A comparison may show something.
Only a couple of Flash Forge printers are directly supported. Others need additional support like plugins or post-processing.

The printer is the Flashforge Adventurer 3. There are no standard settings in the Cura software but I've found a thread here with the settings and applied those. They seem to work fine without support, but as soon as I add support, I get the over print issues.
I've attached the files as suggested. TestSimply.stl
DNX_test 2.3mf
