Content of certain emails do not appear or download

Right-click on the folder and choose Properties > Repair. If it is a Gmail or Gsuite account, right-click on the All Mail folder instead.

All are ok but  emails from
HomemadeTools. net <newsletter@homemadetools.net> used to download normally but only the header shows up. Back in Yahoo mail it is as it should be and the complete newsletter is downloaded. But it is not transferring through to eM Client.
Hope this sheds a little more light on the problem.
Thanks

Can you send me one of these messages? Right-click on the message and choose Forward > Forward as Attachment,

So the message from the server appears fine, but it seems that when eM Client is downloading it, it somehow changes the content.

Are you using a Rule to move these messages to another folder?

No, haven’t changed anything. It was downloading about a fortnight ago and then suddenly stopped.
Thanks for everything. I appreciate it as I am hopeless with computers etc.
Cheers
