OSX Mail in High Sierra stopped showing attachments -

OSX Mail in High Sierra stopped showing attachments - the only hint of attachments I see is the paper clip in the inbox list.

If I open a message, there is NO indication that there are attachments UNLESS I happen to mouse up near the top of the message window. Very annoying and misleading.

In Mail Preferences -> Viewing I do have "Load remote content in message" UNCHECKED.

I refuse to allow tracking pixels and all other remote content automatically displayed.

In my view, any email attachments should always be downloaded - it is not "remote content"!

I have googled many answers to this old issue - none of the suggestions I've tried work.

Is this a fatal flaw for those who refuse "remote content" including tracking?

Many thanks.
