Little Help determining what I’m looking at

Serena

This is my second month charting and I’m just trying to understand this correctly. Per GLOW, I ovulated around CD 12. However- based on my temps it seems later than that. On CD 12 and 13 I got peak ovulation results per the test and I was always under the assumption ovulation happened about 12-24 hours after that.

Any help would be great – all you ladies seem to be pros =)
