New booking additional pet

When I create a new booking that should be a total of $340 it is showing as $230. I believe this is the because it is not counting the rate for the additional dog but it does show that there are two dogs in the booking. Foe some reason, when I input addition pet rates in my settings, it deletes and doesn’t save. I think this may be because I am trying to have some services have he same additional pet price and others have different prices for species.
