Technobeam fixture shutdown issues

For our new install, the producer has brought us technobeams some are Highend a couple are Strand all have different firmware versions all connected to the desk via a path port uno node(sacn) and city theatrical show baby wireless units. We have 4 from hes that don't accept fixture shutdown or lamp off commands from our h4 full boar. They will close their shutters and act like they are taking the coomands but once the console clears and a couple seconds have passed they still are struck. Home, display, and laser commands all work fine. The units in question were all manufactured between nov98 and dec 98 if that helps. We have our old h2 down stairs we just haven't had a chance to dust it off and see if it's the same for it. I've worked on technobeams since 2001 and never seen units ha e issues like this
