qmake does not add all dependencies into generate Makefiles

Rewriting function's code in template classes isn't recognized by the debugger, until line that is calling the functions has been erased and rewritten or if another line calling the function is added.
The images show how erasing a function doesn't prevent it from running as usual.

in main you can see the main running the template functions.
In functions you can see the actual function.
In debugger you can see the program running in the terminal.

1 is before changing the template class's code.
2 is after.
you can see that even though I changed the code - the program is running as usual.
