Hi. I bought the game recently and I'm not very experienced

I started the career mode from the junior level. I've also played tournaments future (obviously losing in the qualifiers

) but my match are over a distance of only one set: they should not be 2 sets of 3? Or is it normal to be so? In the options of choosing the sets there is only in training club but not in career mode.
Thanks.
