All zap extensions report last zap extension number (*65)

As the template notes (zapata.conf.template) I add:
#include zapata_additional.conf in [channels].

If I add several zap extensions and press *65 to hear the extension number, it’s always the last extension entered. I thought it might be because be because the block is commented out “;;;;;;[1001]”, but it’s not. If I uncomment them then I get nothing for an extension number.

Calling the extension works fine.
