pipeline pilot pKa calculation

we're using pipeline pilot to calculate various physiochem properties for our molecules

for one of our projects we're using using glucose-6-phosphate

best I can tell the correct pKas for G6P are 0.94 and 6.11

pipeline pilot only returns a single value of 4.55

can you provide some insight; is there a place to adjust pH parameters, etc.?
