A340 - Throttle Issue

[A320FlightDeck]

A few days ago I purchased the iniBuilds A340. After the iniBuilds A350, this is now my second aircraft from iniBuilds.

I tried to calibrate the throttle in the cockpit of the A340 via the EFB. As my hardware I am using the WinWing URSA Minor 32 Throttle Metal.

In the EFB I selected the two-axis option, however throttles 3 and 4 are not moving during the calibration process.

Does anyone possibly have a solution or an idea what could be causing this issue?

Many thanks in advance. ✈️
