Browsing through tab control does not work while running

[labviewis3]

Hey folks,

my Labview Software has a TabControl which does not work anymore. 
I can click through the registers when the Software is not running, but I can't browse through it when the program is running.

I spent a lot of time trying to resolve this issue and in the end copied the whole thing into a new .vi that I uploaded.

Is anyone able to tell me why those registers can't be changed in running mode?

Thank you

Anna

Make sure it is configured as a control and not as an indicator.
