dialogue don't appear

Hello i'm really try to figure out by myself, but still nothing...
i am tryng to do a dialog scene using the tutorial of Glen, but here no arrows neither arrows.
(see image below)

and the dialogue too seems don't appear. Somebody know why?
thank you in advance

You really should be using png or webp format for all of your image files.

1. create dialog interface in your playable characters dialog area tab.

2. create dialogs in the npc characters dialogs tab.

3. Don't forget to define fonts to use in your playable characters properties tab.

Hello there i set up all these steps correctly, but still nothing to do, i don't see the question and the arrows in dialog area.

Dialog area appear, but don't appear text and arrows

should be maybe a layer problem?

Did you define the text area? There's an icon on the toolbar for setting text area?

Also what OS are you using? Windows? Mac?

Yes already configured. (image below)
I have a windows 8.1

You need 4 arrow images. 2 for inactive state (default) & 2 for active state (mouse over). The dialog interface also has to be created on your playable character. I don't know if Matt is your playable character or not - usually they are placed at the top of the list.

Second point. The dialogs themselves have to be created in the npc characters dialog tabs; however the dialog interface always has to be created in the playable characters dialog area section.

P.S: don't forget to set the dialog choice fonts in your playable characters properties tab.

i right just add the other arrows.
nothing to do,
Matt is an npc, but with an action at the start of the scene "switch to character matt" is this a problem?

ok i redesigned this part and at least i remove the dialog part.
So is not possible to do a dialogue between npc
