I saw in the link you provided in the comment that you are using the old commons booking plugin. The old one is called “Commons Booking”
We have developed a new one which is available on wordpress too. It is called “CommonsBooking”.
We would recommend to use this version cause the old version is not maintained any longer.
There is also a migration / import tool integrated in the new version to make it easy for you to switch to the new version.
