2 issues regarding "Enable experimental features" text

[Mikey1993]

First one:
The "Enable experimental features" is wrong on Crowdin.
It should be "Enable experimental features (Experimental features)"
There is no string of the marked in bold text on Crowdin.

Second one (Adds to the first issue + reported by myself on Crowdin):
IMO, the text should be shown as:
"Enable experimental features (About)"
Because if the "About" was "Experimental features", there would be an odd double translation in the same sentence.

Cheers,
Mike.
