GEL troubleshooting

[Quromen]

I ran dna in a 1% agaraose gel and in 1x TAE, i saw a strange blue region somewhere in the middle of the gel. I used ethidium bromide to visualize DNA. what could that blue region be? I tried to move gel around thinking that it may be the UV light that i am using, but that did not change. I even used another UV machine and had same result.

The dark stains? Bromphenol blue.
