Congratulations on your new Raycast extension! 🚀

Due to our current reduced availability, the initial review may take up to 10-15 business days 🎄

Once the PR is approved and merged, the extension will be available on our Store.

I received this error when I opened the extension, do you have a clue? I tried to swtich my language to Danish to test

19:38:16 Warning: Encountered two children with the same key, `Setapp`. Keys should be unique so that components maintain their identity across updates. Non-unique keys may cause children to be duplicated and/or omitted — the behavior is unsupported and could change in a future version.

@pernielsentikaer thanks for giving a look.
Please give it another shot, I suspect it was duplicate values in one of the arrays
