Help for Aimeos

Hi
Aimeos Version: 21.10.3
Typo3 Version: 10.4.26

Several newly added products are shown as thumbnail. Click on it presents "The product cannot be found"
During adding products there is no error. Data is safed. Stock level I tried different versions.
Just one thing is not clear. In Stock / Type it shows automatically two different. Standard I cannot delete. Even I disabled the Stocktype Default / Standard. see attachment
So what can be the problem?

Is the message "The product cannot be found" in the admin backend or the frontend if you click on a product?

it cannot be found in frontend. As I wrote in product category there is the thumbnail for the product. In backend everything seems to be fine.
Additional info:
I get now in Log thousends of entries ..... product cannot be found. The products which were added before update to version 21.10.3 are visible in frontend as well in backend. The product page of newly added products cannot be found.

If you didn't disable or delete the product, than the product URL has changed so it's not found any more using the original URL segment. Google and other search engines will crawl that URL nevertheless and this is logged in the admin backend.

Thanks for reply.
Pls see attachment - two samples of URLs
green: product is visible
red: product is not visible

I have no idea why this faulty URL is generated.
This is a new product added short ago. With the well known way to add a product.

The product URL segment also contains "-e0a0b-b204b-..." which seems to come from copied products where a small hash is added at the end of the product code each time you copy the product.
