Unable to Cancel to edit Data Backup and Backup Logic Bug in Zoho

Unable to Cancel to edit Data Backup and Backup Logic Bug in Zoho

(1) I'd configured Zoho CRM , database backup for once a month.
I can't change it, there is no edit / cancel schedule buttons around (see attached screenshots), now sure why I can't do it anymore. I used to be able to edit it.


(2) And I figured that I configured the date wrongly and wanted to change it because Zoho has a bug.
- Previusly, I set to 31st of each month. But there is a logic bug in Zoho
- On Months that do not have 31 days (e.g. Sept), it will be generated on the 1st of the next month.(Oct)
- But on October, there is 31 days, on on 31st Oct, it will generate again and charge me $10 for the extra export generated in the same month. (note: It's free for the 1st export generated within the same month)
- And for Feb (with only 28 days), I don't get any export at all for Feb.

Hence I would like to change my monthly export to 1st day of each month instead. But the edit / cancel buttons are missing.

I am on Firefox (MacBook Air), is it a browser issue, that the edit/cancel features are gone?
