Grammar Pop has many errors on the advanced levels when dealing with verbals (gerunds, participles)

I bought and have been using your game in my 8th grade language arts classes. You have MANY mistakes when it comes to participles and gerunds on your game. Many VERBS are marked as VERBALS, and they are NOT. For example, here is one of your sentences.

Jenson was frosting lemon cupcakes this morning.

You have frosting listed as a participle, but it is a verb. It is part of the verb phrase – was frosting. If you put the sentence in past tense, frosting would change meaning it cannot be a participle or a gerund.

Jenson frosted lemon cupcakes this morning.

Please do an update, and correct these errors.
