My apologies... I didn't think it through before my last response.
First, you should be using a query filter in you get items action. See my Get items action above and substitute
field_0 for Date in the query. That will make it so that only items that should be posted to Teams today are returned.
I suspect that you already have the filter because only 1 item was returned.
Because the results for SharePoint are already filtered, you don't need a condition. So, remove the condition in your loop and just have the Teams Post a message action.
Please let me know how it goes.
