Red Text on Lands

[Deadcrows]

Whenever I create a Commander deck in the deck builder, all my basic lands show up in red lettering. Does this mean they aren't legal? My non-basic lands seem fine only basic lands seem affected and it doesn't change no matter what expansion I use.

Funny and interesting question... The "only" basic land im seeing for commander is snow-covered... Wonder why that is............. (to check this i filtered the type and format...) wierd

That means Gatherer, the official database from which iMtG is taking its data, sucks.
