File naming error %premieryear% %airyear% %airmonth% %airday%

Hello Everyone,
I have been using MCEbuddy for about two years. Recently the file rename has not been working correctly.
This is the way I want it to rename my tv show files.
%showname% (%premiereyear%)\Season %season%##\%showname% (%airyear%) - S%season%##E%episode%## - %episodename% - %airyear%_%airmonth%_%airday% Title (2007)\Season 01\Title (2009) - S01E02 - Subtitle - 2009_09_09
But instead I have been getting files named like this.
Title ()\Season 01\Title () - S01E02 - Subtitle - __

I am attaching part of the log showing the error warning.
Please any help is very much appreciated.

Looks like MCEBuddy isn’t able to find any metadata in your original file so everything is blank. The conversion log will show you what it’s finding (or not) in the conversion log.
