Hi @MatiasTonelli1 -
If you're importing Calcite components into your custom app, can you confirm that you're using the version that matches the version of the JS Maps SDK you are using? E.g. Calcite Design System version 1.9.2 is packaged with version 4.28 of the JS Maps SDK, so make sure the version you're importing is 1.9.2 as well. You can find the version of Calcite that the JS Maps SDK is using in the release notes: https://developers.arcgis.com/javascript/latest/release-notes/#additional-packages
Sometimes there are UI issues when those versions are mismatched.
I would also check to make sure the JS Maps SDK stylesheet version matches the SDK version.
