Hi, for you to be able to speed this along tomorrow. I have been looking into myself, it appears the global enable multi-inventory setting is creating the doubling up of the main inventory. But upon reviewing why some are duplicated and other products, I cannot find any difference in the products as to why it is doing this. Further to this, when I switch off the global multi-inventory setting to disabled and try to enable it on a product level it does not save and as soon as I leave the tab, irrespective of saving/applying the changes straight away revert back straight away to following the global rule and disabling its self, again losing the data i just input. So either way I cannot current use the plugin. I have uninstalled and reinstalled and wiped the data. Seeing as the data I had put in was already gone. That did not correct the issue.
