Hi,
I am sorry but we are not expert on Google indexation.
Would it be possible to have a link to your website ? (you can send it by private message if you want to keep it private).
We could check your website and your sitemap, but I am not sure that we will find something ; it's not our domain of expertise.
Regards,

By the way, do not send me private message, use the "contact us" form instead.
