Issue with Lindy Scheduler Sending 'Placeholder' Message Only

Hey Team - I am having an issue with the Lindy Scheduler. Often, when I cc it into an email to send available calendar times, it will just send one word. 'placeholder' and not send the times until I follow up to say 'send the times again' and then it will send them. I have added quite a bit of context to it so i'm not sure if i've overdone it but yeah, it's no bueno. Here's the URL to a task - https://chat.lindy.ai/james-richardsons-workspace/lindy/qgp-email-scheduler-684f346da797de9891381fc4/tasks?task=688882ed992fd76dddb56550
