Tome challenge progress not correct

bm33

I put on the Deadly Race archive challenge, be chased by killer for 300 seconds, at the same time I started playing Yun-Jin Lee for Daily challenge be chased by killer for 120 seconds. I completed the Daily but my tome challenge says I only have 118 seconds. If it wasn't for the Daily I wouldn't know that the tome challenge was incorrect.

Steps to recreate

1. Play public match as survivor on ps4, crossplay on. Have both chase daily and Deadly Race active.

2. Be chased by killer (Spirit was killer in my match) and compare results at end.
