View Page within the control panel

Is there a way I can add the tailing slash when the content editor clicks view page from within the control panel?

The reason I ask is because when they view the page it displays without a trailing slash, but it needs it in order for the collections (list / detail) functionality to work

See here for a working example (With the trailing slash) click on one of the detail pages below - https://extract-technology.com/products/standard-solutions/

See here if you remove the trailing slash (Which the content editor gets when they click view page) - https://extract-technology.com/products/standard-solutions

Any ideas?

Thanks
