Android MT4 Build:1120 (24 Apr 2018) -Unable to filter signal

 
Dear gentlemen ,

May I seek your assistance and technical expertise help ?
My Android mobile phone MT4 Build:1120 (24 Apr 2018) I recently upgraded from previous version 
I am not able to filter the message according to keyword since I upgraded to this version from 24 Apr 2018.
e.g. I like to filter/search for message with "agt"
, but the output does not contain "agt"
Could you enlighten ?
Thank you very much and appreciate
