When I try to change a command block's settings, (like from 'impulse' to 'repeat' or 'unconditional' to 'conditional', etc.) it will not change its behavior. It will actually change graphically when I close out of the command block, but when I go to its settings, it will say it's settings are on 'impulse' 'unconditional' and 'always active', and it will still act like it's on those settings as well, meaning that the command block also does not work as I want it. Here are some pictures to demonstrate the issue:

As you can see the settings for the block type did not change, even with the command block still being purple, whilst acting like it is still on impulse rather than repeat.
