Creality Hi

How to reproduce

Add STL model to the build plate
Add Negative Part -> Text
Type "Test" in the text popup window
Set Depth to be larger than the object's Z dim
Set font height to large (18-18.9mm)
Select the object on the build plate
Right-Click -> Mesh Boolean

Actual results

Only the letter "e" appears cut into the object after the boolean operation.
Attempted multiple fonts and sizes but nun will cut the complete word /text string

Image Before boolean

Image after boolean

Expected results

Expecting the whole word / all letter ("Test") to be cut into the object.
