Command Block Sound Glitch

What I expected to happen was...:
When I clicked out of the command block, I wouldn't hear a deafening sound.

What actually happened was...:
I was looking at the unconditional and conditional button in the command block... and was pressing it a lot... after I clicked out, I almost went deaf.

Steps to Reproduce:
1. type in /give @p minecraft:command_block (make sure cheats are enabled)
2. click the unconditional/conditional button a lot... I mean a lot
3. click done and remove your eardrums.
