Hey @sechix I can't replicate this issue, it seems to be working for me.
If you hit update at the bottom of the product page, does your database match?
Could you post some reproduction steps?
Thanks!

Update product:

After update (even refreshing page):


with es-MX you can see this:

and later I got a missing translation error, I created this PR https://github.com/solidusio/solidus_i18n/pull/129 to fix that, with es, es-EC and es-CL is working fine
@sechix what is the locale that are you using?
I have the same issue. Seems to be related to localization since I use pt-BR and have the exact same issue. My guess is that the datepicker format has a specific format and i18n changes the default date formats, causing the disconnect between the actual value from the input and the datepicker's display
This line shows how the datepicker format uses i18n to decide the datepicker format. This seems wrong to me, as I imagine the datepicker will always accept one specific format, so it should be hard coded.
To expand a bit: on the context of solidus_i18n you see a field called spree.date_picker.format and it makes sense to localize that to the local format. However by doing that you break the datepickers on the admin (haven't tested others, but I imagine everywhere that this helper is used will give the same result).
I propose we hard-code the datepicker format to something that always works, since this is not a presentational value but instead a value that is used by a third party library.
