Tied notes are not played correctly in guitar parts

1) Create a guitar part in a new sheet

2) Make two notes tied together, for example 2 quarter notes tieds together

If you play it with the default guitar sound, it sound as it should, BUT

3) Add a text notation to make the sound of the guitar saturated or distorted and when you'll play the song, the two notes will be played as they are not tied.

I put an exemple below.
