Summary
Fixed a calculation error in Planner 2.0 that displayed incorrect guest counts and total costs for certain occupancy scenarios after saving.


Issue Details
When using a Double + Single Supplement pricing model, the system was failing to correctly aggregate totals for costs that only had Single rates defined. Upon saving the cost, the Planner would revert to incorrect guest totals and financial sums in both the budget view and the cost details tab. This was particularly problematic for accommodation costs where the guest count is the primary driver of the total price.


Resolution
The calculation engine has been updated to accurately handle Single rate logic within the Double + Single Supplement pricing model. The budget and cost views now accurately calculate and display the guest count and total cost for these specific occupancy scenarios, ensuring that planners have an accurate view of their margins.
