Rainwise 1-wire gauge registering 2 tips when should be one

I thought i fixed my previous issue with my Rainwise 1-wire rain gauge but after lots of testing over the weekend i have found a new issue.

In the 1 wire viewer software when the bucket tips it registers as two tips instead of one on occasions. Its an intermittent fault and doesn’t happen for each tip of the bucket.

Would this be a hardware issue or software? Anyone else come across this before??

Cheers
