Considering you were banned for 1 week, it means that Sentinel was the cause.
I can't say for sure that the cause of ban was your double clicking, but Sentinel
does ban people for clicking too fast because they may be using a macro.
If you think that it was a mistake on Sentinel's part, feel free to make an appeal at
https://appeals.cubecraft.net/ using the appeal code it tells you on your ban message. Just say what happened at the time that you were banned, and they'll look into your ban in the Anti-cheat logs. Make sure to mention your mouse.
If that didn't work, you can always talk to the anti-cheat developer (CrazymanJR) on the Cubecraft Discord by clicking this link:

Alternatively, you can message him directly on discord. ( CrazymanJR#4742 )

Oh well, I went into detail at least.
