I am trying to make an 18"x6" tap off of a 10"x10" main.

When using design line, it keeps adding taps in a weird way (see photo 1)

I am new to the software, perhaps I am doing something wrong...

Oddly this was not an issue earlier (see photo 2 ) but I cannot get this to work.
Any suggestions/help would be appreciated.

Thank You.
