Shortcode showing wrong product on page

Hello there.

I started using WooCommerce shortcodes on my website several months ago and I had no problem till today.
This morning I created a news article and I added the following shortcode:
[product ids="36884"]

For some unknown reason, I don ‘t see the right product. I see instead the product with ID 3401.
I checked the database in search of wrong ID usage, I disabled all the plugin in search of a conflict, I updated WooCommerce. No way, I still see product ID 3401 instead of ID 36884. As far as I noticed, this is the only product shortcode not working, all the other products are shown correctly.

What could be the cause?
Thanks.
