Problems within CURA Preferences

[Snipper 0]

Hi, I have an issue with Cura 2.1.99

After doing some try-and-error sessions with Polymax PLA I found good settings for my specific needs (small solid parts (infill 100%) for technical use with highest possible precision).

Then I created this material in the “Preferences” window (Cura->Settings->Material->Manage Materials )by duplicating the Ultimaker PLA to:

Display Name -> “Polymax PLA”

Brand -> “Polymaker”

I left Material Type, Color, Density and Diameter unchanged.

So far, so good…

But now I want to edit *Properties in [Tab] Information (e.g. Density and Cost) and several values in [Tab] Print settings by first clicking [Edit] and then changing some values.

*(Going to -> Settings -> Material -> Manage Materials, then arriving in the “Preferences” window)

But….

After editing values, then closing all, even Cura and then re-opening Cura and Preferences I find the changes I made undone!!!

Exporting and re-importing profile gives no solution, grrrrrrrrr!

And why are some Properties (e.g. Filament cost) grayed out and therefor anyway uneditable???

What am I doing wrong, or…… what is the real problem?

Might it be due to the fact that Cura 2.1.99 is Beta? (Why called 2.3 on download?)

Yes, profiles are still not working properly.
