Either it's because you're betting on an extremely volatile event, in which case, just accept the odds that you get after they are updated; or there is a bug, although the latter is unlikely given that they've patched the old one.
If you still believe that the former is the issue, I think the best thing to do is to email their support.
It may take a while based on my past experience for them to respond, so you should try PMing them as well.
once it gives decreased odds confirm those odds wont give error, that's not good
Then most likely, it's got to do with the volatile nature of the odds. Unfortunately, as a bettor, these are odds that you have to accept.
thanks for the help dear, seems like it is sorted now and its working fine, was on the move thats why was unable to post here
