I am not sure what the problem would be other than maybe some issue with how the bounds on the lengthscales are being handled. Did you adjust the bounds appropriately given the new definition?
Can you post your test case?

I think this has been fixed by bdaa640 . Dividing the lengthscale by 2 before the sum operation seems to be more numerically stable.

Oh whoops just realized that commit wasn't actually pushed to master. I'll make a real PR out of it
