Re-directs not working despite the products being hidden.

I have tried to re-direct 16 products, however they have not appeared in our re-direct list and they are showing up 404 pages even after I have hidden he products.
Please find the URLs below:

Is there why these should have taken more than 18hrs to be re-directed?

Thanks
