wrong theme showing shop

hi, on this webpage: new.gekkepoppen.nl/sarah-huren you see the buttons for the different categories (sarah, abraham, etc.) these are placed in the header for the default theme.
When you see this page: new.gekkepoppen.nl/sarah/opblaasbaar
all the buttons are gone. How can I fix this?

Hello,
Thank you for contacting us

This is because you are using different themes.
You can change the theme in the settings
