LED polarity went wrong in PCBA Fabrication

Hi all...the 2 SMT 0805 LEDs on the red layer are in parallel but opposing polarities. They have a common 2.5V but are driven by a Low or Hi digital 5V signal to select which one lights. The thru hole LED placement is a DNP item which I have as a bicolor LED option. Now the PCBA manufacturer installed both SMT LEDs in parallel , same polarity so I cannot select which one lights independently. I note the tplace layer shows 2 square dots close to the centre point with orientation info.
So I don't know which file in my gerbers to locate what went wrong. Can anyone give advise?
