Problem with 1st time program command

I'm noticing a situation where after a reset, my program statement fails. If after the failure I press the start again, the program statement will succeed. My script is below.

NOTE:

The 1st program statement has two references to %MFG_TEST% as the statement

"-command: program nrf52 %MFG_TEST%,NULL,NULL" fails

Also, the retry parameter does not seem to apply to program

Upon further evaluation, it seems the program statement has an issue with the three variables for programming the nrf52. The following seem to be required.

1) The statement program requires three files, application, soft device, and bootloader. However, the documentation states that only one file is required and the others are optional. If I use NULL for the file #2 and three the statement fails. Typically when we are using Zephyr as the application, a Soft Device file is not needed.

2) I have my program statement coded up as the following:

command: program nrf52 %MFG_TEST_NAME%,%MFG_TEST_NAME%, NULL

Occasionally this works just fine, however, most of the time the first execution of this program statement fails and a restart is need, and usually passes after the first execution.
