Problem exclude itens, modules and menu items

Good night.
I'm using with InStyle joomla3 and delete all of the original template (demo), articles, modules and menu items, even emptying the recycle bin, remained in the database. Also cleared the caches and nothing happened.
I had to delete all items directly into database tables.
This is a problem with the joomla3 or a problem with the template?
Because as soon as the client to enter several articles and content that will be a problem if the exclusion does not happen, because the database is very large.
Looking forward to return, regards,

Hello,

It is a first time when I see a similar issue - it must be an issue with Joomla or your specific server configuration.

I installed InStyle quickInstall of you, that is, joomla3 came with the package.
My server is dedicated and have installed multiple sites that are already using joomla3 without this problem from occurring. Including the template you the Music. So, I think the QuickInstall is in trouble, or there is some InStyle template file with problem, since other sites function normally.
Its you verify this?
Looking forward, regards,
Marcia

Please try to add a new article and then please check if it still exists in the database tables.

Thank you. Now work. The article was included, deleted, the trash was clean and was dropped from the bank.
Because in the attached image, you can see that the trash is empty and the old articles are still on the table (before).
What did you do?
But now it's working.
Thanks & Regards.
