is this accurate?

I recently did a composite chart on this site called "astro-charts.com" and it seemed fine, it showed that I have a Grand Trine and a Kite with my bf. I re-did the same composite on another site and it showed no trine and no kite. The aspects don't seem too changed but still, do we have the trine or not? What do you think, is astro-charts accurate?
