Bugs! Bugs?

[Freire]

First of all, I'm new member and have used little of hp prime capabilities (Bought 5 days ago).
I'm not expert in HP calculators at all and made everything out of tutorials and the HP Quick Manual and the User Manual.
So I just think these are bugs and must be looked at.

My calculator:
Software > 2016 08 29(10637)
Hardware > C
OS > V0.048.635

"Bug" 1 :
Open the Statitics 2 var App, then go to program (shift 1):
Running these commands inside a program:
L1:=MAKELIST(X,X,1,373,2);
L2:=MAKELIST(psat_t2(X),X,274.15,646.15,2);// Common iapws-if97 function [1]
L3:=MAKELIST(X,X,350,587,2);
L4:=MAKELIST(B23p_T(X),X,623.15,860.15,2);// Common iapws-if97 function [1]

In List editor everything looks ok:
L1 187 values, L2 187 values, L3 119 values, L4 119 values.
Then go to Symb and Enter:
H1> L1 L2
H2> L3 L4
Go to plot. Everything works ok.
When you exit this and go to List editor:
Lost all lists and this is shown instead:
L1 0 values, L2 152634753 values, L3 810876928 values, L4 819033182 Values.
(Results may vary but always in a pattern like this one.)
Usually after this happens the calculator behaves in a strange manner, and resets.
??? Should this happen?

"Bug" 2:

Parametric and Polar apps:
When using Degrees instead of Radians, the apps doesn't work properly on plot view.
The plot setup for T range or Theta range are set properly only to Radians view. (Haven't tested Grad, but probably same issue.)
If you still set everything up for the Degree to be plotted propperly,
the zoom autoscale works in strange manner not focusing the plot propperly. (Usually autoscale something like just a 1/4th of the image.)

"Bug" 3:

If you create an App with an external program deppendance and you by chance delete the program (Not the app) the app loses it's properties. (Let me explain)
I created the app from example (Dice Roll) from statistics var 2.
After that Deleted the RollDie() program from the program list.
After that the App Dice Roll (Copied from Stat.var2 started to show as Function copy and all Function app properties without any changes.) But not functional to calculations in any sort.


Thanks for the attention if you read everything and sorry for my english (probably with some errors lolz).

If pictures are needed I'll update this post later.
