[10.2.2] How can the toolbar under the ribbon disappear ?

[hittony]

Hi,

We combine TM1 Perspectives 10.2.2 and CAFE 10.2.2 on Excel 2010 to create a sales planning tool for an automobile company.

A suite of Excel templates to commit data were designed for the planners. Sometimes the CAFE toolbar, which contains the refresh and the commit button, disappear, often after some classical Excel formatting by these planners, such as column width changes, conditional highlights, etc.

Can anybody kindly share his experience and explain how can the toolbar disappear ? What's the reason ? How to solve it ? Is it really related to Excel formatting ?

Regards
