Problem with System Recordings and more than 12 entries

I’m using FreePBX 2.3.1 and Asterisk 1.4.14 and I was doing a demo with the Bukt-in recordings, and some pre-made recordings; after I added the 10th item on the list FPBX got extremely SLOW, to add more fields, then when I pressed the Save button it took forever for the frog to come up. And what a surprise when I checked the IVR entry for that recording ti just played 12 items of the 15+ I had added. On the Asterisk CLI I see them going trgu Ok with no errors but It just stops playing after it reaches the 12th element, and throws me back to the previous menu.

Is this an Astereisk bug, or is it a FreePBX 2.3.1 issue?.

Has anyone had this behavior before?.

I’m clueless here, thanks for the info you can proivide me with.
