This stuff is easily fixed in direction. For the pilot, Zach and Tara were doing pretty much everything and they ended up wearing a lot of hats for the first time. Directing voice actors was one of those roles they had to cover with no previous experience and unfortunately it shows. The voices are recorded first, and without experience, it can be difficult to know if a take is any good or not without being able to see how it pairs with the actual movement of the character (which obviously happens much later). Plus, in the heat of the moment, you can kind of become shell-shocked during a recording session. It's exciting and nerve wracking and if you're not used to it, you feel like a fish out of water. You may feel uncomfortable giving direction, not know how to do it, or perhaps be so overwhelmed by the experience that you don't know whether a take was good or not.
Zach and Tara are both animators first, which is why the pilot LOOKS awesome, but was a little rough around the edges in other areas. Now that they've done it, it's a lot easier to approach the same task with more confidence and agency (and the knowledge of what not to do). That said, if the show got picked up, it's likely that a dedicated and experienced voice actor director would be there to help run sessions and translated notes from Tara and Zach to things the actors can use.
