OPK: Different Results

Question!

Glow says I’m supposed to ovulate tomorrow, so I’ve been testing since Saturday to track. Today I finally got an unblinking smiley from Clear Blue Advanced. However, my strip test isn’t showing a positive. Thoughts??

*When I only had my strip test inputted, Glow moved my ovulation date to Friday. However, when I inputted the digital peak result it moved the date back to tomorrow.
