How to update custom labels after upgrading from v13 to v17

Hi,

after upgrading from v13 to v17 I can see the leftovers from angular {{}} in the block titles. How can I remove this? I don’t find it on the usual place.

I found this article about UFM, but where should I put it?

Thanks

In the blocklist or blockgrid datatype configuration… Where you’ve specified available blocks.

Block List | CMS | Umbraco Documentation

Ahhhh, thank you I was searching for it in data type for each separate block (element type) but didn’t look into the block grid.

THANK YOU.
