By making a new booking at the system, you will be able to see the availability with oversold in the following way:
For example, the category "Chicos" has available 5 out of 19 total cars (10 are for Oversold) Meaning this Category has really 9 cars, and by adding 10 oversold ones, creating a total of 19 cars, with oversold options.
The "Medianos" category has available 8 cars out of 8 total cars (100% of oversold)
Meaning, this category has really 4 cars, but adding a oversold of 100% it ends up with 8 cars with oversold options.
The same happens with the Oversold "On Request", a message of "On Request" will be shown beside the category that was configured to have an Oversold On Request.
