MikroTik SFP Module

Hi to all, excuse me for my poor english.

I noticed a problem on the SFP modules Mikrotik mod. S-85DLC05D that there is’ a problem on the value TX Power of the ones dated 05/06/14 and the ones dated 08/13/14 (See attachments) How can I fix? This is a firmware problem?

The modules are mounted on CCR 1016 and RB921UAG


Regards.
