Master frame - Rendering vary on different page

[Albert]

Hello,
I created a master page with a text frame as a footer zone. I created a style and apply it to this frame and its content. The style contains 2 tabs, one 'center' tab and one 'right' tab.
When I create new pages and apply them the master page, the rendering is not the same for every page 
What am I missing ?
Thanks for your help !

Show us what the differnces are in the page output. Also page3 and page4 images are the same. It might clarify the issue if there is supposed to be a difference between them.

Hello,
Thank you for your answer.
As you can see, in the page 2, on the footer frame, text overlaps as if tab was not correctly handled and the page number is completly on the right, glued to the end of the frame.
Page 3 and 4 display correctly (and are slightly different : page numbering is not the same). And there is a gap between the page number and the end of the frame which I understant beeging the rendering expected with the "right" tabulation.
I expected page 2 be with the same rendering as page 3 and 4 (modulo page number of course).
