It's common.
Did you try moving it around in the order of the macro yet?
Also, sometimes adding .5 sec delay (or longer) before & after the command in the macro will get it working.

With TVs, I usually have it as the 1st command in the macro. Since these devices are the ones I tend of have seen that problem with the most.

Additionally = To test, delete all the other commands from the macro except the TV power off command and test it. If that fails, then you have a different issue going on. Check the routing of the base station (if using one) from the main page vs the device page.
