Descending slide out not playing when a note already has Ascending slide in applied

Hi, there is an issue with the slide ins and outs. I have a whole note with an ascending slide in and a descending slide out but the slide out is not playing.

Also one question about slide ins, is there a way to configure the anticipation or duration of those slides? Cause when using it in a whole note apparently makes the slide in start earlier than when it is applied to a quarter or eight note.

Thanks in advance.
