OnStep with OnStepX 10.03k

I am starting testing OnSteX and even if things seem to work so far there is an annoying thing with polling.
The polling interval stays at 16s whatever setting I use under "Options" "Polling Period".

The same driver does behave normally with OnStep 4.24j polling 1s or even 500ms if I want.

I would like to know if somebody else observed this or is working on that issue before I start changing the code.
