Can't find email

I have an email which I can see in my Inbox on my phone. However, on the computer and in eM Client, it is not in my inbox. When I search for the email it does appear in the search results, but I can’t tell where eM Client is finding it. It is not in the Inbox, Spam, Trash.

So how/why would it be in the inbox in the cloud inbox, and on my phone’s email app, but it isn’t in the eM Client inbox.

And where is it finding it when I search for it?
