Opening time beyond midnight

Hello,
If I try to set the opening and closing times to go over midnight, I get incorrect time slots offered for collection. The incorrect time slots vary depending on which times I pick and the time of day I create an order.

For example if I set the shop opening time to 5PM, and the closing time to 2am, then try to place an order at 1pm, I’m offered the following descending time slots for collection :-
5pm, 4:30pm, 4pm, 3:30pm, 3pm and 2:30pm.

Would the ‘Store Timings and Delivery Cutoff’ extension allow opening times that span midnight ?

Thanks.
