Deactivated Corporate Card Expenses Become Active Again 1 Year Later

Summary

When we deactivate corp card expenses we find they automatically become active again one year later.

We manually deactivated some corporate card transactions which had been paid outside of Fusion two years ago.  These transactions automatically became active again one year later showing up on the employees' lists of outstanding charges so we deactivated them again.  Then again, they became active this spring. 

Does anyone else experience this?  Is there a way to permanently deactivate transactions? 

They are appropriately paid and classified as such in AmEx's system.  It's only in Fusion that they keep cropping up as active.
