Delete indicators ?

[TNA22]

Hello!
My NinjaTrader 8 platform contains indicators, as next picture:



Of course there is no problem with that, but when I tried to read the correct way to delete indicators from platform, I watched the following video about it
https://www.youtube.com/watch?v=p-yJuoRarLk&t=19s
Look at (0:33) in video,
But when I tried to delete indicators in the same way as the video, the indicators is not found in (Remove NinjaScript Assemply) list, as next picture:



Why does the indicators not appear in (Remove NinjaScript Assembly) list? I need the indicators to appear in this list to be able to delete it. So how do I appear it in this list?
Please note:
Also, the indicators file does not have any indicators, Next picture:



According to the video (2:14) , this file is supposed to contain indicators and should not be empty.
So why on my device this folder is empty and does not contain any indicators ?

So the question is: Why on my device does the file not contain any indicators ? And how can it be appear it?
Thanks

Hello TNA22,

If the indicator is not listed at Remove NinjaScript Assembly, please go to Control Center-->New-->NinjaScript Editor. Double click the Indicators folder and check if you see the indicator in question there. If so, please right click the indicator and select Remove. If not listed there, please contact the vendor or creator of the indicator for instructions how to remove the indicator.

The location in your last screenshot shows the templates folder for indicators. This folder does not contain indicators, but templates that you save for indicators. Indicators are located at Documents-->NinjaTrader 8-->bin-->Custom-->Indicators.

thank you very much
But (Ninja Script Editor) is not allowed, so how can it be made allowed?
