changed lyrics not syncing

I have an iPhone 4 running iOS 5.0.1, an iMac running iTunes 10.5.3.

I have previously synced my iPhone with iTunes, and some of the songs have lyrics.

If I need to make a change to the lyrics for some reason, (mostly because they don't format properly when viewed on the iPhone, or they have the wrong lyrics listed), once changed and I then re-sync the iPhone, the new lyrics do not come across.

I have even deleted the playlist from the sync list, run the sync again, made sure there was no music on my iPhone. That seems to be working the way it should.

Then when I select my music again in the sync list, and re-sync my iPhone, the old lyrics still appear on the iPhone. The new lyrics are no-where to be found. Everything is still proper on the iMac in iTunes, but not on the phone.

I even deleted the lyrics on iTunes, synced my iPhone, and the lyrics were still on the iPhone they should have been gone.

Just wondering if anyone else has had this issue and found a way to fix it?

It looks like once the wrong lyrics have been synced over to your phone you can not fix the issue. I do not want to restore my iPhones firmware just to fix this issue, which looks like it should be a simple operation.

Thanks.
