CSS no longer recognising as it should be written categories (they seem purple) in WordPress Further CSS

I’m the use of Further CSS at the WordPress marketing strategy and feature been the use of the inspector to seek out the names of the categories I need to edit then modifying them and not using a issues till lately.

I discovered the identify of the category I need to edit ( .wp-block-group.is-layout-constrained ) and replica/pasted it into the Further CSS textual content field, when I deleted the surplus textual content round it as an alternative of turning gray to suggest that it’s been recognised as a category it stayed purple to suggest an error.

I then attempted reproduction/pasting the categories I’ve already effectively edited they usually too now gave the impression purple.

Does any individual know what may well be inflicting this and the way I will be able to repair it? Thank you upfront.
