Purchase of medium supply pack with repair time that disappears into thin air

Hi there, I bought a medium supply package. When I loaded the 6 hour repair time from the supplies and resources tab it did not register although the required supplies points were available. I have to load it by opening my base, going to my army, go to repair time and then load it from the drop down menu and then only it registers. How can I be assisted to get the value for my purchase back cause I now seemingly "lost" it and it seems to be a bug that needs attention
