LMK04828: TICS Pro Issue - VCO Frequency Not Setting Correctly

I am trying to use TICS Pro to configure a LMK04828B. Ultimately, I need a DCLKOut8 of 156.25 MHz. To achieve this I need a VCO frequency of 2500 MHz (2500 / 16 = 156.25). However, anytime I try to input 2500 MHz, TICS pro changes the value to 2520 MHz. If I try to change it again, its as if it just ignores it. Not sure how to proceed. Thanks!
