Hi,
This indicates either a javascript error or an issue with the CSS.
So there are two things you can do:
- On that page, open the console of your browser and check if you have any javascript error:

- In the HikaShop configuration page, under the "Display" tab, check the backend CSS option. There, you should have "default" selected. If you have something else, like "custom", it's likely that you have customized the backend CSS of HikaShop and that you've based yourself on the default CSS file of an old version of HikaShop for that. Because of that, you didn't get all the new CSS since then, including the CSS of the checkout workflow editor. So revert to "default" and reapply your CSS changes to this new default file if necessary.
