iPad Email Attachments showing up as empty/missing icon question mark

So this is a very odd bug that is happening on both the iPad and iPhone os, albeit it occurs more on the iPad.

When I sent PDF attachments that shows up on my normal apple mail (as a preview PDF inside the email content), it is showing up as a empty icon in the ipad mail even though iPad mail does note it has an attachment with the paperclip mark.

Keep in mind my email acct is synced over imap on the iPad, iPhone, and apple mail. The pdf attachment opens in apple mail without problems.

This problem also occurs on my iPhone but it is less often.

I hope a described the problem well. If anyone like to see the email for themselves contact me at uunders@gmail.com and i I'll forward you the email with the PDF attachment.
