If you browse to one of your own pending suggested edits, accessed from your user activity page, you are directed to the suggested edit in the review queue. Example: a review item. There, the message
This item is not reviewable.
is displayed. As written, the message may be patently false; I see by refreshing:
This item is not reviewable.

I guess it was reviewable after all. Clearly, it's meant to say that the item is not reviewable by you, since you're the one who suggested the edit.
The same applies for things like Low Quality Posts tasks where you previously flagged the post, or Close Votes tasks where you voted to close externally, etc.
Please change it to something like "You may not review this item.".
