Error with Click and Collect service

OS: Linux
Aimeos Ver: 2021.10.4
PHP: 7.4.12
DB: MariaDB

I'm getting an error when choosing the default installed Click and Collect deliver service:

Configuration for "supplier.code" is missing
Invalid service attributes

I get this after I enter the time and try to proceed to the next step.

This is a clean fresh install of Aimeos and the shop sample.

Did you select one of the listed suppliers in the Click&Collect option from the demo setup?
You can also remove supplier selection if you don't need it by removing the "Supplier" decorator in the delivery service option.

I had not changed anything, I tried to use it as the default entry from the fresh build.

To fix it I had to remove it and re-add, now it works.

However the date and time picker works only for Chrome, it does not work for firefox properly, there is no style to it and not user friendly.
Could you please advice how to change the time picker style or to a different UI, thanks.

Firefox only allows to change the values of the time input field but doesn't offer a dropdown like Chrome. If you want to offer that regardless of the native browser implementation, you need a JS library you can use for that.
