double slash “//” in directory path for child theme

Hi, I’m using the custom templates for geo-my-wp posts locater in my child theme and experiencing issues with the style – for instance grey grid isn’t showing as a grid.

The directory path url for the style sheet is showing up when inspected, as having an additional / in there after the geo-my-wp file – I can’t see where it’s coming from.

The url looks like this: my-child-theme/geo-my-wp//posts-locator/search-results….

Has anyone come across this issue before?
I checked my wp settings for a trailing slash, and the permalinks, nothing there…..
Thanks in advance for any pointers I’m a bit stuck!
