Scripts that pull Excel columns not stacking properly in JMP 18 vs. JMP 17

[#1]

Hello.  I have a script that takes input from Excel files and stacks data, etc.  I've attached a small sample of the script along with a sample excel file, in 17 the end product is two columns (the desired output) but in JMP 18 extra columns are generated and my very involved scripts than do not load/label data properly.  I get the following error in 18:

at line 50 in Z:\Data\Michelle\Automation\Scripts\JSL Control Scripts\test script.jsl

Does the first table look same? If it does, you might have to make small changes to the settings, such as dropping all extra columns (it defaults to keep)

Both JMP 17 and 18 have Keep All as default, but does give me some ideas to investigate.  Thanks for looking at this.
