Power Planning in 45 nm_SOCencounter

Hi my friends
i have a problem in add strip in 45 nm tech
when i add strip i see this warning in shell window
"
**WARN: (ENCPP-2008): AddStripe option -remove_floating_stripe_over_block is ON so all fragmented stripes within a block will be removed.
To turn OFF, setAddStripeOption -remove_floating_stripe_over_block 0.

Starting stripe generation ...
Stripe generation is complete."

and when simulation was finished i have a error density ( in verify density metal
) which have been shown in below, of course i have this problem for any design with any Die size (large or small) and this problem was not solved with changing layers

"******** Start: VERIFY DENSITY ********
Density calculation ...... Slot : 1 of 1

A total of 34 density violation(s).
Windows < Min. Density = 34
Windows > Max. Density = 0

******** End: VERIFY DENSITY ********

can you help me?
