It is typical. It may bee that you have removed all of the guard bees, which is what I like to do before removing the comb. It does make them calmer. They may not go into the hive because there are too many in there working hard and creating a lot of heat.
I do know from watching the Observation Hive that for the next 3 days the bees will ignore the SHB and the beetles know it and will come from long ways off to infest that hive.
It you have a SBB (Screen Bottom Boards) with an oil tray, on the 3rd day you will start to see lots of larva and beetles being removed from the hive.
If you have a STB, (Screen Top Boards) you can remove the cover and kill 20 to 30 SHB every 24 hours on top of the window screen for the next week. They are beetle magnets even after the beetles start reacting to them.
