Bot "Left to pay" total bug

I have a pot that I pay all my regular bills out of and it’s always worked well. However recently I added a loan payment to the pot and the “Left to pay” total hasn’t changed.

When I edit the scheduled payments I can see the £400 loan payment in the list and even if I remove it and then re-add it the “Left to pay” total doesn’t change.

It’s only been a problem with this particular payment and I have been remembering to simply add an extra £400 to the pot, but it would be good if it could be resolved.
