Hydrobrake Minimum Outlet and Node Diameters for Large Flowrates

We have noticed that for high Flowrates (100l/s and 380l/s) on a recent project that the Hydrobrake Min Outlet and Node Diameters do not populate and return a zero value.

It is our understanding that this part of Flow is using the API provided by Hydro International. However, we wondered if there is a way of flagging the error in Flow, e.g. red warning with recommendation to contact Hydro International directly.
