Issue: Some (not all) dates are piped into an email from a sharepoint list are incorrect (off by a day)
Here is my flow:

Here is what I have for the deadline:
formatDateTime(item()?['Deadline'],'MM/dd/yyyy')
This flow creates a list that I get in my email that looks like this:

However, some dates are imported from Sharepoint correctly, while others are off by a day (one day later than they actually are). In the same example, the highlighted dates are behind one day.

I wonder if this is because I need to convert the time? If so, is there a formula someone can help me figure out how to write it to ensure dates are all coming in correctly?
Thank you in advance!
