Thank you for waiting.
I have re-checked your issues.
1. Map is not showing in single page. I have checked it and tried to deactivate “«Line-R» — Sticky Music Player” plugin and it works. You can check it again.
2. I have checked your issue. The problem is when you create the room using german language you did not yet assigned the room for this hotel so it didn’t show on page. Please assign any room for hotel.
3. I have checked your location issue again but it still works. I can still save location on other language. If you need to, I can record video for you.
