white grout turning YELLOW...Help!!

A few months ago I installed some basic white Home Depot tiles in a shower surround. I used AcrylPro mastic with some basic white Polyblend non-sanded grout. I sealed it with Aqua Mix Penetrating sealer a couple weeks after install. The shower has not been used yet...but I'm noticing a strong yellow/orange color coming through the grout. Now I have a nice white tile shower with yellow/orange grout lines. What is causing this....and how can I get back the nice white grout lines?? Thanks in advance

first guess would be the mastic is bleeding through cause it wasn't dry or it reactivated when you grouted and the moisture has nowhere to go but out through thr grout joints
