Hi Claire, thanks for getting in touch :)
We've made those buttons editable by you via the Construction Zone. If you look in your Home folder (once logged in) you'll see an item there called Quick Links. It's got a cross next to it so it doesn't show up on the indexbar. Click on the name 'Quick Links' then in there you can delete that particular link. You can also add others here in the future and they'll show up.
You'll also want to delete the Beep App page under Home > Information.
In addition to this, I'd suggest you add an Absences Notification form to your website using our Forms tool. It provides another avenue for parents to submit an absence directly from the website.
I've copied Natalie in on this email. She'll touch base with you to run you through how to do this. You could even add a quick link that points to the form from the homepage :)
Have a great week! :D
