assigning different template for user profile

Hello
My social network is now 9 users. I use a variant of Gantry template (voxel) to the user profile.
All profiles are shown in this template with the exception of the 3 oldest created profiles. They show default template.

I think it must be for one of two reasons:

a) any change in CB after 3 oldest create profiles and this keeps them showing default template
b) create the new template after making 3 first profiles and these are not affected by the new template.

I have no idea of ​​the diagnosis and therefore can not find solution.
You can give me your opinion?.
Thanks

I've no idea how you're assigning Joomla templates to different profiles, but Joomla normally does this using Itemid and all of CB uses the same Itemid for every profile. If your Gantry template has more advanced template assignment features you'll need to check with them regarding it as I've no idea how their framework functions.
