Competitive placement matches lost

This season (since OW2 release) I’ve played a number of competitive role queue matches trying to get initial placement.

I’ve been dropped in as both tank and heals. I was having more success as tank than heals. Yesterday I finished my first heal placement, so I switched to tank to finish my placement. All of my tank placement matches that I have completed before today are missing. They are present neither on my career profile nor the comp placement screen. Is this related to the resetting/miscalculating career profile screens?
