how to reset a bit from a global DB at the end of PLC scan cycle

Hello everyone!

I'm looking for advice. I have misunderstanding how to reset a bit from a global DB at the end of PLC scan cycle correctly.

I have test DB.

I want to set bit ".out" depending on the condition of bit ".in":

And I want to reset bit ".in" at the and of scan cycle:

But a have the issue.

I'm setting bit ".in" by double-clicking it at DB window at field "Monitor value". But bit ".out" isn't changed to "TRUE" reliably. One time I do double-click one time for changing. Another time -- 5 times, etc.

Help me please, why is it working so? Where can I read about it?

I know, bit ".in" can be reseted right after FC_SetBit function. But I want to have one certain place, where I can put all bits I want to reset regardless to where I use them in the program.
