The plugin does not work as it should

I would like to rate this plugin which has potential and works correctly most of the time. It is very useful, but sometimes it happens that there are really serious errors that break my entire website, but now the plugin doesn’t work as it should. On the days when I have normal working hours, it gives me a day off and I don’t want that, and it also gives me bad times there: we are open until 7:00 PM but it only shows me until 5:00 PM What it should be?. It would really like to completely fix this plugin to make it flawless. As I say, the plugin has potential because it is probably the best that exists so far in terms of booking, but these errors spoil it unnecessarily.
