Hi there!

Thanks for your query.

You may use the following code snippet in your custom CSS:

body.view-transports .topbar-search-options.spbooking-top-filter {
    display: none;
}

Note: Path towards custom CSS(Joomla 3): Extensions>Templates>Styles> Click on your current default template name then choose Template Options. Then find custom CSS within the custom code.

You can try to change the 'day' word for your transport part within the component's language file. Here is a screenshot for your ease:

Here is the path: /language/en-GB/en-GB.com_spbooking.ini

Hope this helps!

Best Regards
