slider title issue

When i select slider then i see inside tiny editor this
[su_slider source=”media: 303201″ limit=”35″ height=”400″ title=”no” autoplay=”3300″]κλουβε? ματ[/su_slider]
from where is located the κλουβε? ματ ???!!!
ALSO
In the case of youtube shortcode, I put https://www.youtube.com/watch?v=QwX_5HdUvyU as the URL and besides it it shows me in the shortcode (text editor) and url = https: //www.youtube. com / watch? v = R08zGbHLqws that I do not see has any relation to the youtube video I introduced.
