midi remote control problem/bug?

i have a midi keyboard controller, which has some additional buttons ect on it. when i record remote control actions in app settings (under note input), the notes C, B natural and D don't work in some octaves (lower ones), but when i clear the midi control options, all the notes can be played and used for input normally.
Thank you in advance for your help, i really appreciate the app ...
Best regards
