Issue with /gamemode in command block

When using the /gamemode command in the chat box, it works just fine, putting me in the right gamemode. However, for some reason when I type /gamemode creative or /gamemode c in a command block and power it, it switches me into survival mode, and when I try /gamemode survival or /gamemode s in a command block, it switches me to creative mode. After doing some quick testing with switching to adventure mode, moving the command blocks, etc., I think the issue was caused by the fact that the command blocks were directly next to each other. For some reason, when I put command blocks next to each other and place a button on each one, the buttons will activate the command block beside them instead of the one the button is placed on. Maybe it has to do with the behavior of chain command blocks, but they're both normally orange ones and facing away from each other, so I don't know why it's happening. I love to build small, simple command block contraptions such as this one in all my worlds, so I'm kinda sad they're all broken now. I imagine it's probably a simple fix, just tweaking some sort of timing or a few redstone powering values, so I'm hopeful that this may be fixed within the next 2-3 patches. I believe in you.

Unrelated side note: Thanks to you wonderful people at Mojang and the wonderful game you've made, my entire career plan for the future is to invent a hit new game, become a somewhat well-known game developer so you might want me, then sell my soul to you 😊 Thanks so much for being awesome and my biggest role models! 😁😘
