You might recall there were reports Kendall and Kylie's company got slapped with a notice at their NYC office ... claiming the sisters had fallen behind on rent to the tune of more than $57k and had 5 days to pay or get the hell out.

But, a rep for the leasing company tells TMZ ... it never should have happened. The company says, "There was a miscommunication due to a change in invoice procedures that led to this confusion. We apologize for any negative press the Kendall + Kylie brand has received."

The leasing company went on to say, "They have always been respectful and in good standing tenants."
