Josep,
Does the array still show directivity? If not, there could very well be a bad
component.

Gut suspicion is that you have a relay with fused contacts or blown
coil or some such, and your ACTUAL connections inside are not not what
you would be expecting from the schematic. Or maybe a burned up trace
or something.
