Followed the instructions on the language/translation tab in the plugin.
Uploaded the translation to the folder and now there are parts that are not translated.
For example, in the check availability search, The Label of the field appears in English but when I pick the date the months already display in Finnish as well as the days of the week. Also the button with the label search.
I would suggest that you submit your request to our Help Desk, providing a temporary access to your WordPress dashboard, so we take a closer look at the issue.
