Automations modified in the Eve app with multiple conditions show up in the Home app for me, though what I do is make the automation in the Home app first and then editing it inside Eve since my automations primarily involve individual accessories and not scenes so the Home app is better to start with for me than Eve.
Out of curiosity I tried making a new automation directly within Eve first, setting multiple conditions and it shows up just fine in the Home app.
I don't know what to suggest here to help, but have you tried re-installing the Eve app so that it asks you to give it permission to access your Home data again just in case? Though I'm not sure if the Eve app will ask for this again or if it will already have the Home data access cached unless you perform a Reset Location and Privacy, in which case you can simply try disabling and enabling "Home Data" in Settings -> Eve.
