I cannot reverse the direction of the router for the Associative Dado Machine Token by changing the value in Parameter 2. Has anyone have the same problem and was able to solve it?

I am using Microvellum OEM 2019 with Build 20.1.617.641. I do not remember trying to change the dado direction since upgrading from V67 a few months ago. I know in V67, it worked. But in V67, Parameter 2 was only Reverse Direction unlike the new Toolbox which has 3 options. From reading the release notes of previous builds, there was an issue with one of the options that was resolved. I'm not sure if that affected the Reverse Direction option.
