Inconsistent values from Versaprobe

I'm using QTDragon HD and having issues when probing.

I am using the steps as outlined in the qt_auto_probe_tool.ngc file start off with.

From machine_log.dat (VIM line numbers precede each line)

Here's the popup message:  NOTE the MDI line number 231 has no Z axis movement and the program file has not even started to execute. At this point the new tool change has already taken place and the new tool is being measured.

 

Not sure what is causing this but, after I "Clear all" the and restart the file from the beginning it runs as expected without the error.

Finally, worth noting is that I noticed my tool table appears to have been altered and is NOT from previous runs. Has many missing columns.
It appears as if something has written to the tool table when it should have not.
Here's a couple of lines in my current tool table that reflects this issue, note that tool 16 has the Z set.

T15  P15  D+6.350000 ;whiteside router bits - whiteside ru210
T16  P16  D+6.350000 Z+258.012190 ;whiteside router bits - whiteside rd210
T17  P17  D+6.350000 ;whiteside router bits - whiteside rd207

And here is a backup that I took a week or so ago:

T15 P15 X0 Y0 Z0 A0 B0 C0 U0 V0 W0 D6.35000 I0 J0 Q0 ;whiteside router bits - whiteside ru2100 -- 1/4 inch upcut spiral- solid carbide 
T16 P16 X0 Y0 Z0 A0 B0 C0 U0 V0 W0 D6.35000 I0 J0 Q0 ;whiteside router bits - whiteside rd2100 -- 1/4 inch downcut spiral- solid carbide 
T17 P17 X0 Y0 Z0 A0 B0 C0 U0 V0 W0 D6.35000 I0 J0 Q0 ;whiteside router bits - whiteside rd2074a --o-flute 1/4 inch downcut spiral - solid carbide 

Any ideas?

 

So, the call to save the tool offset is in the qt_auto_probe_tool.ngc on or around line 202-203 seems to be mangling the tool.tbl format.

203 G10 L1 P#<tool> Z[#<calculated_offset>]

Which occurs after the OKAY click of the tool change prompt. I've checked it before and after.
