I have checked all the layers in Layers panel. But in Presentation mode, there is icons are showing up which are unwanted

Hey @The_Yellow_Submarine ,
This is odd! Can you make sure that you haven’t activate the ‘hidden’ layer option to your icon. You can check it in your layer panel (left panel).

Here is how the layer’s visibility works;
You can also toggle a layer’s visibility in the Layers panel. You can toggle layers individually, or hide all child objects in a group or Frame.

1. Hover over the layer, group or Frame in the Layers panel.
2. Click on the visibility icon to toggle the layer’s visibility off.
3. The eye will close and the layer will be hidden in the canvas. It will also appear as inactive (greyed out) in the Layers panel.
4. Click to toggle the layer’s visibility on again.

Please also note when you hide a layer, you won’t be able to select it in the canvas. This includes using the Select layer option in the right-click menu. You can still select the layer in the Layers panel and by showing outlines.
