Scaling inaccuracy

I'm attempting to increase the X, Y scale of a storage bin STL to match a real-world storage bin I want to copy.  When I scale up the STL to match the X, Y measurements, slice, and print, the resulting object measurements are not what the Cura scaling shows:

 

Cura:  X 135 mm, Y 181 mm, Z 76 mm

Printed object:  X 81 mm , Y 145 mm, Z 76 mm

 

Z measurement is accurate.

 

Here's the first part of the GCode:

 

;FLAVOR:Marlin
;TIME:35508
;Filament used: 34.6484m
;Layer height: 0.2
;MINX:97.935
;MINY:77.503
;MINZ:0.2
;MAXX:232.913
;MAXY:258.781
;MAXZ:76
;Generated with Cura_SteamEngine 4.13.0

 

I'm using the latest Cura version and an Ender 5 Plus.

    It's also including the platform adhesion in the size in the header. That's why the x & y are different but the z is the same.
