OSC control - Custom Down Timer

Is there a problem with latest h2r graphics and osc control? I wan’t the send a custom down timer with a pre message via the stream deck. I can’t overwrite the timer with a new value. If a timer is already set, even if it’s not visible I can’t set a new one with osc string.
With /h2r-graphics/timer-custom-down-time-of-day it works as expected and I can overwrite the timer. But with /h2r-graphics/timer-custom-down and /h2r-graphics/timer-custom-up it seems not to work. The timer keeps the value sent before.
