Data lost after entered into Contribtor

[hydrojoe]

Hello

We have some users who have been entering data into Contributor and when they hit the commit button the data stays 'blue' and doesn't turn black. When I go check their transaction log files in the Tm1 folder they don't have any transactions but they have a file .cub_delta extension??? I can't seem to understand what this is used for?

Can this be used as a recovery file?
