When Mia and Mel step back to have their side conversation after Claire offers to pay their debts and to invest in their company, Mel brings up both hands to shield her lips from Claire's view as she speaks, resting the fingers of her right hand on her left palm. When the shot changes to the opposite side, she is holding up only her left hand.
When Mia and Mel are waiting in the Oviedo reception area they knock a drone out of the air and put it in Mel's purse. One of the drone's propellers is broken. Yet later it flies out of the purse with four working propellers.
When Mel is shown chopping up "ghost peppers", there are no seeds in the peppers and she is shown handling the peppers with her hand which would leave oil residue that would irritate any part of her body she touched.
In the end, when Shay tells Claire that Mel & Mia still own 49% of the company when in fact they owned 51%. Therefore, she owes them $510 million instead of the $490 stated in the scene.
