Jo sharp instructions

Using Jo Sharp Village, Essential sweater. On inc row she instructs " Inc 1 st, k to marked st, up 1, k marked st, up 1, k to end. After repeating this row, an odd #of stitches are increase.
What is “up 1” and how can two rows yield an odd number of increases? :??

I haven’t been able to find anything, but could an up 1 be a M1 increase? Makes sense.

As for the odd number of increases, how many times do you do the increase row? Would that result in an odd number of increases?

HEY! Look what I found!! Corrections from the Jo Sharp website.

ESSENTIAL (pg 39)
The abbreviation for ‘up 1’ is actually the same as ‘m1’ in the abbreviations at the beginning of the pattern pages.
Sleeve shaping: line 7 should read inc 1 st each end of foll 8th rows 12 times, NOT 10th rows as stated…this gives 96 shaping rows NOT 120 as stated.
Collar shaping - 4th row down says Knit 8 rows - it should say Knit 9 rows.
This changes the Next row to (WS) and the following row to (RS).
Graph - The “Make Ringlet” symbol are in pairs, therfore the first and last symbol on rows 1, 5, 9, 13, 17 & 25 should not be there.
