my fitness app and health app not syncing

My health app and my fitness rings are not syncing for one specific day ( 17th of June ) despite multiple attempts to add/delete exercise minutes/ activity energy as well as workouts the data is not adjusting for that specific days.

I do not have an issue with any other days.

I have unpaired and repaired my phone and Apple Watch as well as deleting software and updating to most recent iOS on both the Apple watch and the iPhone. I have restarted it multiple times as well as turned off location services and airplane mode and turned them back on without success.

The issue originally started when I accidentally added a 6hour workout and in deleting this workout I deleted the full days recording but am wanting this rectified to reinstate my activity streak as I had nearly 300 days worth.
