Mistakes Found

Question

I noticed a few mistakes here in this lesson. In some areas, for the "tu", "ellas/ellos", and "nosotros/nosotras" forms of "acaber" there are double "ba" syllables. For example, there's "acababas" instead of "acabas", "acababan" instead of "acaban", and "acababamos" instead of "acabamos". I've double checked elsewhere to verify the correct spellings of these forms and nowhere else did I find the double "ba" syllables.

Hola K Plus M.
Thanks for your observation.
What you're seeing isn’t a mistake, the forms like acababas, acababan, and acabábamos are actually correct conjugations of “acabar” in the imperfect tense. This tense is used to talk about past actions that were ongoing or repeated.
For example, acabábamos de llegar means “we had just arrived”, which is a common and correct use of the imperfect in Spanish. The repeated “ba” sound is simply a result of how the verb is conjugated in that tense. 
In contrast, acabas or acabamos are present tense forms. So while it may look unusual at first, the “double ba” is completely normal in the imperfect tense.
Hope that helps clarify things!
