Help with zombie saves in steam's remote folder

For some reason (why???) steam cloud has ancient WoTR saves that download to my Steam\userdata\[]\1184370\remote folder instead of the usual Appdata folder and I cannot get rid of them. I have tried all the tricks I know to wipe cloud saves from Steam's server (using the steam console, deleting while in game, turning off cloud sync, deleting, then re-enabling, etc). But this manifest from 1184370\remote only seems to sync down, never up. Anyone have any ideas or will I have to live with the zombies cluttering up my drive in perpetuity
