What is the process for executing a correction deed?

I purchased a flat from a builder in Pune. While executing the agreement for sale, the date was missed on the first page of the agreement. My photo, thumbprint, and all signatures were completed on June 11. However, I noticed that in Index 2, Section 9 states the date as June 11, while Section 10 states it as June 12. When executing the correction deed and referencing the original agreement, which date should be considered: the date in Section 9 or Section 10 of Index 2? (Note: I am not inquiring about the date to be corrected on the first page, but rather the reference to be given for the original registered document.)
