Woocommerce grouped product in cart not displaying product image and name

Hi,

after a major Woocommerce 3.0 update our grouped products are not displayed correctly. First there was a problem with not showing the child products on the main product page at all – but with one of the updates that was fixed.

The problem now is, that even thoug the products are grouped, when they are added to cart, there is no description of the main product.
For example we sell different products and each of them has two options of packaging (10 bags or 200 bags). When one of the options is added to cart, it only says 10 bags without any info which product it is. There is no way of knowing what customer ordered.

Is this another bug and we should wait for another Woocommerce update?
Does anybody have the same issues?

Thanks in advance!
