i can confirm such problems, but i had to add a even more worse problem created by a “similar” Environment
i had repeater with 4-5 row before, 2-3 with no value inside url-field.
after add true/false field and set required like described above
i add 6th repeater row, because of not filled required field save fail.
i check/uncheck true/false field and try to save again.
strangely enough that works! but this bug happens:
inside url field a value was filled that came from a other row. but not only inside the new row, it was filled inside every empty hidden url field.
(fortunately i dont need such a setting at productive state, but that need of course a fix as soon as possible)
If someone had the time he can test: if it happens with all conditional field inside repeater (like checkbox, radio-button, select, …) and if it happens to other fields than url too
