Why "model.Interval" converted to "IntervalUnit"

[eriksoftwaredev]

In "\src\Web\Grand.Web.Admin\Controllers\ProductController.cs" Line 2572, "model.Interval" is converted to "IntervalUnit". Maybe it is a mistake. The code: (IntervalUnit)model.Interval

I want to let vendors set reservation calendar with different interval units. For example: In Mondays, just daily. And other days 12 hours. Is it possible?

Best regards
