Does this only happen if the original bulb state was off? Or does it also happen when it's on? I'm asking because the Hue Bridge (I'm assuming these are Bridge bulbs) does not accept color or level commands in conjunction with a command for bulb on/off state, so it's likely either Hubitat only sends the latter or it does but Hue ignores the former (can't remember off the top of my head if it throws an error on the Hue side or if it just silently ignores it, so I'm not sure what they would have chosen to do).
This issue recently came up in another thread, but I'm not sure the poster ever tried exactly what I suggested (for one: for the purposes of testing, only manipulate the bulb from Hubitat to avoid refresh-interval issues) and provided a clear answer afterwards as to whether it worked, but perhaps you could see if it does for you:
