Notation error in STUDY

I was using 'STUDY' option. I opened 'THE LONDON SYSTEM' in the 'INTRODUTION' chapter there is a notation error
After d4 - d5, Its is showing 'Lets use the move 1.e5 as an example' it should be 'd5' i think.
Thank you. Please let me know if i am wrong.

Hey,
Studies are user content. If you found an error, your best shot would be to contact the creator of the study
