Why is Aramaic "tlasah" used for wine in ketoret, where spices are counted in Hebrew "shlasha"?

In Talmud Keritot 6a, read in the siddur, it states,

קילופהשלשהוקנמוןתשעהבוריתכרשינהתשעהקביןייןקפריסיןסאיןתלתאקביןתלתא

Why is the Hebrew שלשה used for "three" (hin) in counting קילופה, cinnamon,but the Aramaic תלתא used for the wine? Is there any significance?

Thanks for any help on that.
