TYPO3 Core

We have the same issue on a TYPO3 7.6.15.

It occurs not on only on tt_content, but also on sys_categories, pages_language_overlay and others.
Additionally, pages_language_overlay does not respect if a sys_language is set to hidden.

I can confirm this for TYPO3 7.6.23. Can someone give a hint, what the origin of this issue can be?

it seem i have the same issue here - TYPO3 8.7.10

Still having this problem in TYPO3 8.7.24. Has someone an idea?

I tested this TS property on 6.2.31, 7.6.32, 8.7.26, 9.5.7 and 10.0.0-dev (latest master); and so far I've seen that

- it seems to affect only the "make new translation of this page" link in page module > languages view
- It works only on 7.6.32 and 8.7.26 (and only for the link I mentioned)

I don't know if it has ever meant to work as described on this issue; the documentation https://docs.typo3.org/m/typo3/reference-tsconfig/master/en-us/PageTsconfig/Mod.html#disablelanguages just says:

Comma-separated list of language UID which will be disabled in the given page tree.
