I seem to be having a similar problem with only some ‘choose a page’ links. After exporting the code and loading onto my server the link structure is wrong i.e. it should be www.mysite.com/test/client-company-profile.html but is erroneously appearing as www.mysite.com/company-profile
I have reselected my ‘choose a page’ links several times with no difference. The problem only effects some links and always the same ones.
ps. I should add the links are not changing back to ‘choose a page’ they are holding the chosen page.
