Masks duplicate after saving effect and applying to another clip

Hi Yusuf29330304fy4o,

Thank you for filing a bug report, I have not been able to reproduce the issue you are having with duplicating mask after applying the dust and scratches preset to other clips.

However if you give us more information, such as the version of Premiere Pro you are using and your workflow steps we may be able to help out more.  Below are instruction on how to write a bug report, once we have more info we will see if there is a workaround for this. Thank you again and look forward to hearing back from you.

Bug reports are not only for addressing for Premiere Pro issues. You can also file them for Premiere Pro documentation, like the user guide, and other support documentation.

In the bug report, it is very important to write precise steps describing how developers can reproduce the issue you are seeing. The developers can fix reproducible issues. If the issue is not reproducible, it is difficult to fix.

Use the template below to provide us with information: 

• Issue - A short description of the problem. 
• Adobe Premiere Pro version number: FAQ: How to find the exact version of Premiere Pro you're using?
• Operating system - Windows or macOS, and which version of those operating systems?
• System Info: CPU, GPU, RAM, HD:

  • CPU

  • GPU (Intel-based Macs and PCs)

  • GPU driver (PC)

  • RAM

  • Hard Drive (and, if external, how the drive is connected: USB 3, Thunderbolt, NAS, etc.).

• Video format: Provide information about the type of video you're using. For example, XAVC-I 4:2:2 10-bit. If you're unsure, let us know what settings you selected on the camera. Sharing a sample file is useful if you don't have access to the camera. 
• Workflow details: Tell us any specific info about the project or sequence. For example, is it a multicam sequence?
• Steps to reproduce - (Very important!) In a numbered list, the exact steps are needed to reproduce the problem. 
  
• Expected result - What should have happened after the last step?
• Actual result -  What did happen after the previous step? 

Optional but helpful: upload media, project files, screenshots, or screen recordings demonstrating the issue.
