UWL configuration issue in EP 7.5

Hello,

Greetings!

We have customized UWL 'Tasks' tab adding some extra columns. Custom view loads fine for the first time when user logs in. But when user clicks on some other tab in UWL (eg. tracking) and then comes back to Tasks tab, instead of custom iview, standard uwl iview is loaded.

On Logon -> UWL->Tasks tab has 10 columns

then user clicks on 'Tracking' tab.

Again user clicks on 'Tasks' tab -> user sees only standard 7 columns.

Has anyone faced this issue?
