Load/ Load & Print (problem)

What is the problem?
I have a 'wait' gcode to insert a nut during a print, if you use 'load' and then click the 'print' button on top it stopped and the pause button is activated, I can insert the nut, click 'pause' and the job continue, what is is suppose to do, however if I use the Load & Print shortcut (file area) the printer pause but the button show only 'start' printing, then it is impossible to continue, rather frustration if you are two hours in the printing phase. I use version octoprint 1.3.8 with cura 3.2.1, and the plugin to pause at a specific height. Is it suppose to be different ?

What did you already try to solve it?
Use the workaround, but I sometimes forgot the short cut key does work, and clicked it, ...
