Warning
If a Rate that you select in the ‘Select Rate’ popup was ticked on the Rate sheet results screen, then that Rate and any Rates below it will have a TBA Rate once the override is complete, e.g. If you select 3 Rates (see image below) but select the second Rate in the ‘Select Rate’ popup, then the first Rate will be overwritten with the settings of the second Rate as expected but the second and third Rate will be TBA Rates.
Why?
This is due to the system first clearing the Rate of its original settings and then copying over the settings of the Rate selected in the ‘Select Rate’ screen.
