This is expected behaviour when combining Adobe Launch + gtag.js instead of using GTM I believe. GTM isn’t broken — it's just telling you: "I see a Google tag fired, but I didn't fire it!" and Adobe Launch is doing its job — it’s firing the gtag() calls.
When tags like gtag('config') or gtag('event') are triggered outside of GTM (e.g. from Adobe Launch), GTM’s Preview/Debugger mode cannot identify them as GTM-managed tags. You can keep using Adobe Launch – ignore the “Unknown” label in GTM or migrate Google tags to GTM for clearer tag control and easier debugging.
