Hi,
As I said the issue is a caching issue.
So you need to turn off the caching on have on the breadcrumbs module and/or the caching you have on your pages and the problem will fix itself.
Unfortunately, there is nothing we can do to avoid that as the problem is not in HikaShop but in the way the caching is handled for the breadcrumbs module which is a Joomla module, not a HikaShop module.
HikaShop will provide the current breadcrumbs on every pages (unless the whole page is cached) and then it's up to the module to use them, which it will do unless it is cached.
So to solve the issue, you need to turn off the caching you have on that module.
I don't know how you configured the caching on your website so I can't say precisely what needs to be changed where.
