Any updates on fixes to the playlists page issues?

An Update:
For issue number (3): As I was debugging, I found that in the file bootstrap.min.css, .dropdown-menu had "display:none". So, i commented this tag however, now, the edit and delete menu options show all the time rather then when I click on the down-arrow beside the icon. How can this be corrected?

The other remaining issues remain unsolved:
issue number 2 - Set as current icon does nothing or sometimes gives an error on player (Error loading player)
issue number 4 - is there a way to edit or create playlists from backend?

New Issue:
issue 5 - Also, I was able to change the name of "On-The-Go" inside my language override so it appears in arabic chnaracters. However, when you click on the playlist itself, the playlist name on the page comes as On The Go rather than the arabic named one. Also, the page heading and breadcrumbs show the english name not the arabic. Same issue happens on the main playlists page (http://lfandev.com/playlist).

The warning error is now gone after I added "$this->playlist_session = new stdClass();" on line 121. I did not want to completely re-install the whole component as I have made a lot of styling adjustments for RTL in many of the asset-css and views-tmpl files. Now, the error is gone however, these points still remain unresolved on playlist page:
2- Clicking on "Set as current" on a playlist for the first time gives on error on player (Error loading player) and then clicking it again does nothing. However, when you click on the playlist name itself and refresh the page or go back, it loads up fine in the player
3- When logged in from frontend, clicking on the "settings" icon does nothing. Also, unable to edit name of playlist nor delete the playlist.
4- Unable to create playlists from backend nor edit anything in them.
I also noticed that in the demo, when you click any playlist name, the pages opens with the name of the playlist on the top. However, on our website, I do not see the playlist title.
Your help is greatly needed and appreciated.

I have looked at this discussion and I did re-install the component and the error is still there. Besides, I have other issues as well besides the error. Also, I forgot to mention that our website is RTL. Can you please help me fix the issues with playlists?

Greetings. Have you looked at this post yet?

Since it is a similar problem, it could fix it. Download and reinstall the components the support has mentioned there and see if it solves the problem.
