In a character sheet, Spells page, while selecting spells through the "Manage spells" sidebar, the ritual tag "R" doesn't appear for some (not all) ritual spells.

Examples : Tenser's floating disk, unseen servant, illusionary script.

It works in the character builder at least (as a work around).

What class are you playing as?

Wizard

I recall seeing (and confirming) this bug report before. The ritual tag does show up if you use the character builder instead of manage spells.

The ritual tag is only shown when the spell is "learned". Unlearned spells don't show that tag. Hopefully, it can be fixed so that it is always shown.

 Hopefully it does get fixed.

As I mentioned twice before: unlearned ritual spells display correctly in the character builder, but not in manage spells.
