Hello,

as you can see from the title I have a very strange behavior while trying to implement a new reader using a python plugin.  
When the reader is automatically loaded from the PV\_PLUGIN\_PATH after opening e closing paraview two times all the settings are restored to the default values.  
But, when I put the python file somewhere else and load it via Tools-\>Manage plugins-\>Load New (and also select Autoload), the reset does not happen.  
Attached you find a example of the reader giving the issue (I added the `from paraview.simple import Show` to the [the CSV reader](https://github.com/Kitware/ParaView/blob/master/Examples/Plugins/PythonAlgorithm/PythonAlgorithmExamples.py) ).  
If you put it into the PV\_PLUGIN\_PATH, you should be able to reproduce the error.  
NOTE: It only happen with 5.10.1, no problem with 5.8.1

Hello @mwestphal ,

thanks for the quick answer.

You can copy the reader attached to my previous message to your PV\_PLUGIN\_PATH.  
Open/close Paraview a couple of times.  
It should restore the default settings.  
Thanks,

Thanks for the try, I also tested with Paraview 5.11.  
If we have a `from paraview.simple import *` in the reader, and the reader is located in the PV\_PLUGIN\_PATH and not loaded via the Manage plugin window, I still have the same problem.
