What is probably happening is the email action has ended up inside an Apply to each because Power Automate sees the Area values as an array.
I’d build the Area text first, then use that in the email.
Add a Select action before the email:
From
Area
Map the value as:
item()?['Value']
Then add a Compose action after it:
join(body('Select'), ', ')
Use the Compose output in the email body.
The key bit is to make sure Send an email is outside the Apply to each. The flow should be more like:
Trigger / Get item
Select Area values
Compose joined Area values
Send one email
Not:
Apply to each Area
Send email
That should give one email with all areas listed, for example:
Reception, Corridor, Office, Store Room
