Wrong icon and attachment

I found the support doc on icons not showing correctly for attachments.

Has anyone seen where the attachment is shown as the wrong program?

Example: Attachment #1 is an excel file and shows as an excel attachment, attachment #2 is an excel file and shows as a text file attachment?

Is this the same issue as stated in the below ibm support doc?
