Issues with Lindy AI Not Replying in Email Threads

I have been using lindy as an ai assistant to keep my schedule and meetings however when sending emails it WILL NOT Reply in thread no matter how many times I've tried, used up credits, and even tried to just simply build a new agent specifically for replying in thead to emails it just simply won't work. It creates an entire new email thread can anyone please help me Agent links here: https://chat.lindy.ai/kylie-shipleys-workspace/lindy/kylie-executive-assistant-69092de57687678ef655587d/editor Agent simply for replying: https://chat.lindy.ai/kylie-shipleys-workspace/lindy/email-reply-agent-695a09fe165b3e9ad68a23f5/editor Both when sending email just put RE: as the title of the email but don't actually reply. I've tried everything.
