Silverstripe/linkfield anchor not working

Silverstripe Version: 6.0

How to set up/migrate silverstripe/linkfield to work with manually entered anchors?

I just started to migrate a website from SS5 to SS6 and as I only had three links I wanted to add them manually.
So I clicked on the “Add link” button, chose “Page on this site”, chose the page I wanted to link to and entered an anchor (without the #) as this was what I did when using gorriecoe/silverstripe-link and the description below the Anchor field kind of suggested this as well, at least the first part of it: “Do not prepend “#”. Anchor suggestions will be displayed once the linked page is attached.”

I assume that silverstripe/linkfield isn’t implemented like gorriecoe/silverstripe-link to manually add an anchor. Is that correct or am I missing anything?

If I am correct, what is the best way to migrate those links? I read the gorriecoe-migration guide, but regarding the anchor issue I am still a bit puzzled.
Could someone please point me into the right direction? Thanks
