Conflict by simultaneous use of the "legs" of "end of chourus" along with the TIMES of repetitions command

Can someone please help me? (I may be well having do something of wrong).
I'm italian and use the lenguage italian version.

But, following the instruction manual MuseScore I experience a kind of
conflict with the software actuations given by simultaneous use (that is ncessary to have playng many repetitions over the two) of the "legs") for putting one "end of the chorus" (in italian is the "stanghette fine ritornello") , along with one TIME TO PLAY command, (in italian is "VOLTE" command) which must be used to determine the number of "n" repetitions before jump OVER the sign "legs" end of the chorus.
(In fact, the manual says that the number of these repetitions is to be properly added to the "repeat count" case in the of "property measure").

Indeed, the program performs the "n" repetition I write (for example 4), but
reached the SECOND repetition, the "legs" of end simple chorus are ALWAYS bypassed making
to play the measure that is BEYOND the repeat sign, overlapping in this same time the two audio sounds gived from of the two functions together.

(in other words: overlaying the play at same run after the second, the measure lying beyond the repeat sign, with the sound coming from the proper work of the repetiiton TIME TO PLAY command).

Thank You
