Not able to map mousewheel down (bug?)

[Mora]

Hi, I'm trying to map the left encoder to work as a mousewheel (While it works as an axis trimmer which is done already) Using a "2 AND boolean" to map it to another physical button while reguiring another button to be pressed. Everything works otherwise perfectly, but I'm not able to map one of the buttons to mousewheel down. Even if it says down it works as mousewheel up. There must be a bug in the software. Maybe someone could discover a workaround? This is important to me because I used a Saitek throttle previously, and it had an encoder working as a mousewheel I'm very accustomed to.

S-TECS MODERN THROTTLE STANDARD STEM XT2 v2.189
VKB Device Config v0.93.17

Set a non-zero mouse wheel speed in the logical mapping dialogue. +0 and -0 are the same.

Thanks! The X-65F throttle is no longer better in any way.
