CSS Flyout header with Multilanguage EZ-Pages

I installed flyout header on 1.3.8; all working. Then I added French Language Pack - still working. Added copy of headermenu,php to langages/french/extra_definitions/my template. Still working.

Then, I added Multilanguage EZ-Page mod.

When I add the french translation to the EZ-Page, with no changes all all in page title or config, the title disappears off the flyout header. In place of the missing title there is a blank bar, about half the height of the other titles in the menu.

And if you click that blank bar, the EZ-Page indeed appears correctly. So the page is there and the link is there, even though it is invisible.

This is all on test site w local server so can't show.
