Hi.
After all updates of IMC this bug is already present in my implementation.
It is not highly urgent for me and I don't know if it affects only my system.
But if you manage to solve it I think is better...
I'm using IMC v.2.5.7 on Joomla v.2.5.19 and the IMC-Mobile app for Android v.2.0.3
Best regards!
Giuseppe.
