Place the marker at the beginning of this round. There's also a marker after the first repeat of the whole section from the asterisk. It sounds as though you're marking the sides of the sweater at the underarms.
The pattern really should have parentheses to mark off the section to repeat 5 times, like this:
* K11 ,m1,(K 22, M1) 5 TIMES, k11, pm rep from * once more
12 sts increased
So it's only the k22, m1 that is repeated 5 times.
Maybe this isn't a cardigan or do you cut the knitting to make the front opening?
