Please add more information. I'm not sure what you mean.

The url above points to the wrong URL, which is new.

Can this be added to the quarter？

[Ovilia]

What do you mean quarter? You may use Chinese if it's clearer.

Maybe it's about Quarter {Q} format in String Templates
{Q} formatting is working as intended Demo Code. Wish it could allow bold or font settings somehow.

@helgasoft Thanks for the help. It's possible to be bold using rich text.

By default, the most primary level is in bold style and it may be bug right now and should be fixed in #17311.
