Cutting the connectors does disallow for the deck tiles to be connected to the edge pieces. We have had some customers use Liquid Nail to adhere the deck tile to the trim but this solution has mixed results, and is not officially endorsed. If your deck tiles are installed over a wooden deck, you could also screw through the trim into the wood underneath, after pre-drilling, using a trim head screw. With that said, we currently do not have any official solution to this issue and would recommend installing the deck tiles in way that minimizes cutting them, such as starting at the edge and leaving the cut pieces for the edges of the deck against the wall.
