Cache problem in module with Jumi

[ldor]

Hi,
I've recently enabled cache in my Joomla site because this is supposed to make the site faster. But now I have problems updating the content of a certain module. The updated content does not show up on the page. The cache time is default, 15 min, but the content does not show up even after 1 hour. I've disabled caching for that module but that did not help. The only way to make the updated content show up is to delete all cache on the site. Does anybody know how to fix this?

And by the way, for the content that is shown in the main area, not in a module, there is no problem.

Disable the System Page Cache Plugin

I've checked, this plugin is already disabled.

It just came to my attention that the content of this module is pulled by Jumi plugin. But I don't see anything related to cache in Jumi configuration. Besides, I've found another module where the content is pulled by Jumi and that module gets refreshed if the content is updated. I really have no idea what is different about the first module that it does not get refreshed when caching is enabled.
