No warning for schedule overlap in Solidres

Sadly I found a big mistake in the programming of the component from Solidres. Until the "Status" in some reservations in the reservations list is on "Pending arrival" bookings for the same room at the same period of time are possible. This is OK! But if you change the "Status" in one reservation to "Confirmed" and also try to do this in another reservation with the same period of time a warning should be absolutely necessary. But no warning is coming. So for one room two guests will be arrived at the same time and the hotel will be in big trouble. Exactly because this would have been quite often happens in hotels the programmers had to be more careful for this problem. Do you already know about this problem.

This is 3rd party solution that we only use - please contact their support and report the bug.
