Two Identical SmartThings (IM6001-BTP15), Only One Offers Double Press?

Added two old SmartThings buttons to my Home Assistant.

Set up the first one to control two bedroom lights: single press toggles first light, double press toggles second light, hold turns off both lights.

So now I went to add a similar automation to control two Ikea smart plugs, but it is only offering single press and hold triggers: why doesn't it offer the same double press trigger the other identical button offers??
