I just wanted to make sure the change wasn't intentional. thanks.

In particular, instead of a 10k and a 1k, I got two 10k resistors. At least 2 different endstops had the wrong resistors, I have not checked the other 4. Is this an intentional change from the gen 3 electronics on the site or should I dig up some 1k resistors on my own?
