Who I have the same questioned this topic

I am using Message Plus on my new Droid Turbo 2. I received several text messages while my Wi-Fi was turned off.

I then deleted the text messages I had received (while the Wi-Fi was still turned off).

Later, I turned the Wi-Fi back on.

ALL of the Incoming Text Messages I had deleted (while Wi-Fi was off) began bombarding my phone as if New.

Does anyone Know why this happened?

Is there any way for me to prevent this from happening?
