Predictions Capitalized in middle of sentence

Many of my words are predicted in a capitalized form, even in the middle of a sentence. It seems like I get the capitalized form more often than lowercase, making the prediction nearly useless. I keep removing these words but it keeps happening. There's got to be some way to get the app to only show capitalized words at the beginning of a sentence or when typed that way much more often than in lowercase. Or when typed in all-caps repeatedly. Or baring that, just only predict lowercase words. Because those are used far more often, most words are NOT at the beginning of a sentence.. This is an extremely annoying and time wasting problem.
