Selecting by category does not work in overviewmap

I use an addin to add categories and tags to Pages. I’ve also tested with my Posts too.

I’ve been doing a lot of testing to try to get to the bottom of this. I think the problem is my use of Polylang for multiple language versions of my pages. I have two categories, one for each language. On a map I am showing the markers for the appropriate language by specifying the category for each language in each of the two versions of the page. This is not working – it picks up both language pages. Although there are two categories – the fact they are linked as different languages for the same category means your code gets confused.

To work around I’ve added two dummy categories and don’t link them for language. I can then select the pages I need.

It would help if your code worked with polylang. I think it will be a common use case to show just markers for the right language.

Thanks for your testing efforts too.

My new workaround (appears to work) is to have two sets of lat lng in differently named custom fields for the two different language pages. I then set latngs= to the language group I want. Bit of a cludge but it works.

So not sure if you want to support use of polylang …… would be helpful … but there is a workaround.
