Hello Rockz.
We cannot do that, you need to do that, and the process is simple but we repeat the advice every year. Here’s how to do it on a PC, but if you use another device you will need to adapt these instructions:
To delete last year’s tags:
a. Go to the “Tag Butterfly” page
https://www.monarch.org.nz/wp-admin/admin.php?page=tag-butterfly
b. Hold down the CTRL key on your keyboard and tap the minus key (next to the zero) so that you can read the [Submit] button at the bottom of the page.
c. Mouse over the [Submit] button and click – this will remove the tag number in your dropdown menu. Continue to do so until the first tag for this current series shows up.
PLEASE BE CAREFUL! The first time I did this I nearly deleted some of this season’s tags. Keep checking by using the down arrow next to the tag number, to see how many are left to be deleted.
Oh! And when you’ve finished hold down the CTRL key on your keyboard and tap the plus key (next to the minus) so that your page returns to the usual size.
Hopefully at some point we will be able to get this process automated, but until then you will need to be doing it yourself.
Please remember to place messages in the “Research” section of the forum.
