If you are making a reason that contains a parenthesis (), the parenthesis and everything inside it will be ignored.

i'm using banmanager v5.9.0

(example below)

[21:31:03] [Server thread/INFO]: weboy issued server command: /tempban the_cam_guy 1s test, dont mind this (really dont mind this)
[21:31:03] [Craft Scheduler Thread - 271/INFO]: The_Cam_guy has been banned by weboy
 - Reason: test, dont mind this
 - Expiry: 1 second

This is a feature. In your case there was a player note created called "really dont mind this".
This can be disabled in the config here.

I have noticed that even when setting this to "false", it'll still create the note and shorten the reason.
