Facilitate ease of formatting citations/references across devices with the same account

I have Endnote X8 on my desktop and laptop and I have different record numbers for citations across the devices thus, I cannot use the unformatted citations across devices because the references are not recognized. This means that I cannot use either my laptop or desktop to format my references/create a bibliography and I have to stick with one device this is highly inconvenient.  And unfortunately, this causes me to compare this faux pas with mendeley and zotero which do not cause this problem. this causes unnecessary headaches and duplications for students like me. 

Please, please create a way to for example; have the record numbers synced via the account and shared across devices to make our lives much less complicated. Thanks!
