Flashing on/off with Aeotec smart switch

I tried searching for an answer, but could not find anything that specifically related to my issue . . . .

I've got an LED strip of lights hooked up to an Aeotec Smart Dimmer 6 z-wave device briefely flashing every minute. I've been using several of these for over a year without any issue. Today, I noticed the particular unit that controls the LED strip started flashing the LED, approx every minute. I tried changing the device type to a generic z-wave switch and see the "Flash rate" option. It was set to 750ms. When I try to change it to "no selection", it defaults back to 750ms. I can however, change it to a larger number, such as 2 sec or 5 sec. This will, as expected, flash every min with the light on for the selected time (ie; 2 sec or 5 sec). Any thoughts?

Problem solved . . .

Apparently, the cord was not plugged in all the way. Maybe it was shorting out bc of the faulty connection. Either way, I plugged it in and made sure to relieve the tension. No more flashing.
