Excel macro VBA issues

Hey guys. 

- I wrote a macro, which contain other macros using Call orders. If I running the macros separately everything ok, from the main macro one of them didn't running it's like it skipped from the list. Reason unknown. 

-On running I can see 4 application window get visible, and those didn't connect any kind of application. Also a Clipboard error message get visible, but I get a Clipboard cleaning macro, which several times cleaning the Clipboard, so it can't be. It's like a hack, or something which I don't recognize.

- One a sheets called Total, I can't use the built in group function and can't collapse the selected section so the project I working on lost functionality. 

I didn't make any change on that side, but previously it was useable. 

Thanks for help in advance.

Cheers.
