Parsys lissues on the template

Hi Guys,

I am tring to add parsys (10) onto the template in AEM 6, but for some reason i cannot drop components from par6 to par10.

So this is how i am referencing them on the template

<div data-sly-resource="${'ipar0' @ resourceType='wcm/foundation/components/parsys'}"></div>

<div data-sly-resource="${'ipar1' @ resourceType='wcm/foundation/components/parsys'}"></div>

.

.

<div data-sly-resource="${'ipar9' @ resourceType='wcm/foundation/components/parsys'}"></div>

is there a limit set for parsys in AEM 6.1

Thanks
