Incremental achievements in GPGS

A silly question… I have everything working fine with my GPGS Achievements, except this little thing that irks me.

The Achievements that I have set as “incremental” always appear with that “circle graph” that shows the % completion, and never with the icon I have designed (even when it is at 0% or 100% and unlocked). In the end, instead of my colorful icons, what I see in the board is a lot of grey circles, and a lot of green circles.

Is this supposed to work this way?
