Is not possible link Template with host using host screen

I have 2 frontends ... frist one with trunk version 2.1.1 and another with the last build of today (2.1.4).

In frontend 2.1.1 works fine the selection of templates to link with host (template association in hosts screen). But in 2.1.4 is not possible to select the host.

The lab enviroment 2.1.4 is node based... i dont know if is this the problem ?
