Issues with Garrisons

Hi! I want to tell you a problem that I had a few days ago. Before the last maintenance (early Monday I guess), I moved three Garrisons. The next day, two of those three Garrisons didn't moved. I can see that they are in "use", but I can not assign units, or send them to attack. I attached two images for further reference.
I contact the support service (Latin America), and they told me was a browser Cache problem (I use Firefox), but both in the laptop and desktop PC got the same problem. I cleaned the history (cache included), as they told me, but I had no solution.
Probably someone has any solution.
Sorry about my bad english and thanks..

Problem solved.
