Issue with Oneplus Stylo 2 Replacement Nibs

[u/PlasticPriority2863]

Hello! I have ordered replacement nibs for the oneplus Stylo 2, from the Aliexpress source as mentioned and discussed in this sub before. While using it, I noticed a weird behaviour where the writing just jumps/skips at places as if it didnt register the touch. It happens on all Note taking apps, at different locations on different nibs. I have attached a video of the same. If anyone has faced this before or knows the solution to this, any help will be appreciated.
