...I have a few questions about the attached tables from the BEP website
It doesn't look like that table is from the BEP's website. It does look similar to the tables that are found at
https://www.uspapermoney.info, but those tables haven't been updated for nearly 5 years.
Where did you see these tables

It's best to go to BEP's production data website at
https://www.bep.gov/currency/produc...tion-reports for currency printing information. It currently is only showing production reports through Sep 2024, but newer reports are usually, eventually posted.
The Jan 23 report on that website does not show any 2017-A $1 FRNs for the Chicago FRB being printed.
The Feb 23 report does agree with what's being shown in your table.
Also, the Jan 23 report doesn't show any G_* notes printed that month.
It's not unusual for the BEP to skip serial numbers in printing * notes. AFAIK, only they know why they do this.
It's also not unusual for the BEP to print a FRB's * notes before they actually print the regular notes. I guess they want them on hand as replacements if something goes wrong with the regular production notes.
Finally, * notes are not replaced with other * notes. If something goes wrong with the * note printing, they're just destroyed and others are printed.
It appears that wherever you got the table from has some incorrect information in it
