A room shows a booking for tomorrow — can I still check someone in tonight?
Yes. A one-night stay runs to checkout time tomorrow morning, so it fits in front of a next-day arrival instead of clashing with it.
A guest arriving at 6pm for one night is leaving tomorrow morning, not at 6pm tomorrow. The system counts that stay to checkout time, so it no longer blocks a room that has a reservation starting the next day.
If it still refuses
Then the clash is real. The 7-day availability strip on the dashboard shows which night actually overlaps — usually a booking that starts today rather than tomorrow.
