Hi I have been in a competition for a step streak for 300 days now and All of the sudden Garmain decides to reset my streak to 2 days :( :( …

i have not missed a day and I really don’t want to lose this competition can you please help.

On my watch the graphs are also showing I haven’t missed :( 

Please get me my streak back, only yesterday it was 290
