How to remove certain lines in multiple txt files?

Hi ,

I have this type of files:-

BGH.28OCT2008.00000001.433155.001
BGH.28OCT2008.00000002.1552361.001

BGH.28OCT2008.00000004.1562602.001

Inside them contains the below:

How do I get those line in green deleted as i do not know when is the last 'calls' line?
And how do I loop to remove those lines in all the txt files?

Anyone can help?
