[BUG] Programmable Device Simulator - triangle wave min/max

Trying to run a triangle wave with min-max = 400-800
In gatway webpage:
Created a Programmable Device Simulator.
Added two 'tags' with Value Source:
sine(400.0, 800.0, 100.0, true)
triangle(400.0, 800.0, 100.0, true)

Subscribing in Gateway or adding the tags in Designer gives a correct Sine, but triangle has min=0 and max=(max-min).

Tried to make the min negative, same result.
