Auto Manufacturer Quality and features

Hi,
I have purchased a few benefits for my auto manufacturer,
and it still shows as 0%.
I purchased updates more than a week ago, have sold all my inventory a few times, and still shows 0%. So, I don’t think it’s a mixed inventory problem. It might be a bug.
Can you look into it?
Thanks

Can somebody check this problem?
Thanks

It is displaying correctly now

Mixed inventory will have an effect, and depending on the amount on hand, the quality and features will take time to rise.

Thank you!
