which I manually (by pressing the button at 2) corrected to April and I thought it is the way it's suppose to be.
The Master Moon and both Master Calendar models all adjust the month after 31 days, which means that there are 5 months when you will need to adjust the date forward via the corrector at 4 o'clock. The months are supposed to advance automatically as the date goes to the 1st of each month.
It sounds like something has gotten out of alignment. I would ship it to JLC and see about getting that fixed.
