Probe Basic DRO display appears blank

Hello,

I recently upgraded LinuxCNC from version 2.9.4 to 2.9.8 and updated Probe Basic to the latest version as well. I'm currently experiencing an issue where the DRO display in the Probe Basic GUI appears blank.

Has anyone encountered this before and could point me in the right direction to find a fix? The Probe Basic simulation configuration works fine and the DRO is visible there, which leads me to believe my configuration file is the main culprit. That said, this same configuration worked without issues prior to the update.

I've attached the machine HAL and INI files in case they're helpful.
