Error message related to units when trying to import AGS file.

Hi everyone. This is the error message I am getting when trying to import an AGS file. 

The file details for the "<UNITS>" lines 544 and 551 are shown below. 

Have tried changing the units to match an old example or deleting the section but then Openground does not recognize this as an AGS file.

If anyone can provide some guidance on how to solve this issue will be very helpful. Thank you!
