The checker shows your current streak if you scroll down below the longest streak.
The checker does not include finds of Lab Caches, you have opted to include Lab Caches in your Profile Stats. Since your longest streak in the challenge checker is an old streak of 116 days I would assume that your current streak have multiple days where you have logged only Lab Caches. Looking at the checker a day like that seems to be 1 July since you currently have an active streak of 2 days, yesterday and today.
The fix here would be to ask the CO if they feel Lab Caches should be included and if so, ask them to request a new checker that includes them. If they don't want them included you'll have to keep streaking without Lab Caches for one more year or chose to not log the challenge.
