Data API returning data from a different table

I’m utilising the bubble data api to export my data and it’s returning data from a table other than the one specified in the URL. Some research has shown that this could be because I changed the name of some of my tables at some point (though I don’t recall doing this). How can I see the ACTUAL keys for my data tables?

Have you tried doing the optimise and clean up actions to remove any of the old data?
