Multiple carriers being ignored, shipping £0

[roastchicken]

Hi

Has anyone encountered this problem :
I have 3 carriers

1. royal mail (0 – 2kg) at £2.00
2. royal mail (2 – 4kg) at £2.50
3. Parcelforce (0-10000kg) at £10

When the overall weight exceeds 4kg, I would expect the Cart to drop into option 3 (Parcelforce) but it remains with Royal mail ( £2.50) ? I then set the ‘Out of range behaviour’ to disable but now when I exceed 4kg, delivery goes to £0 in blockcart. So the cart on the home page does not show correct total.
But when I then goto the checkout, the cart then re-adjusts for Parcelforce and now shows the correct amount.
All carriers are are shipping to the UK from the UK i.e. in the europe zone.

I've also tried the Demo page with the latest Prestashp version and I get the same error and have reported it as a BUG.

Has anyone got a workaround, like removing shipping options until the shipping page OR just use one carrier but when I physically post out I use a carrier I prefer.

Can it have something to do with that you have set Parcelforce 0-10000kg. Have you tried to set it to 4-10000kg?

I remember now i had this problem myself in the beginning. And i dont know if its a bug or not. But i did only one carrier for the both carrier that i use and just set the different weight range in that carrier. Maybe you can do that untill they fix it?
