Page Layout ⇒ chapter inherits style from a previous one?

[daviddoji]

I'm composing the final version of my PhD thesis for storage in the University. I have a small problem with the abstracts. I wrote them in English and French.

When I print the references for the english abstract, the french abstract takes its headers writing in all the pages "References", as it is printed in the references page of the english abstract.
If I don't print the references for the english abstract, the french abstract has no headers (that's what I want).

Please see the example in overleaf: https://www.overleaf.com/3020233swcywv#/8316005/

How could I solve it?

Thanks in advance.
