prop and throttle

[Pop]

In both V3 and V4 there seems to be a "link" between the throttle and prop controls. when I move the RPM lever the throttle moves. At full throttle and full increase RPM, if I reduce the RPM the throttle is retarded as well????
(T-28, A1 and A36) controls set to Throttle(or throttle 1) and Prop set to (prop or Prop1)

In both V3 and 4 using an “axis” to control throttle and prop results in a “goofy” link between the two. Moving one moves the other. Using switches to control rpm + and _ work OK

Sounds strange, but I encounter a similar effect, affecting rudder and brake(s) in v3.4 (not yet in v4.1):
Using the default Beech King Air taxiing on ground, I observe the rudder to 'wave' inadvertently like a flag in the wind, when I use my CH pedals for steering on ground. The front gear shows normal steering movements, and the plane - though sluggishly - reacts to my steering movements.
On the other hand, using differential brakes, e.g.the left side, the left gear creates a dark smear on the taxiway, the plane itself turns to left (as intended), but also the rudder shows a distinct deflection to the left side, moving back to central position, as soon as I release the brake. The same, only vice-versa, when I use the right brake.
Re-running a calibration of the CH pedals (either with the CH Software, as with P3D itself) plus re-assigning the axis assignments does not really change much.
A comparable 'bug'?

If you have not already done so, I suggest you check all your control settings, under 'axis' assignments and make sure that you do not have duplicate assignments. If your plane is a single engine, then use Throttle for your chosen throttle lever, and Prop for the RPM lever. Make sure that your throttle lever is not assigned to both Throttle and Prop in the settings.

Are you using FSUIPC for axis assignment and calibration?

Are you using Saitek controls?
(I do since a few days, and I've got to re-learn sim-flying!)
And it's now spooky similar: moving the prop control moves also the lever for mixture control.
A double axis assignment in Spad.next (from the downloaded profile I use) was the culprit.

I have no such connection between throttle and prop using a Thrustmaster Warthog HOTAS. When flying props, my throttle lever is asssigned to throttle axis and slider is assigned to propeller. Never had a problem. As suggested, check all your assignments and if you are using FSUIPC try moving the fsuipc.ini file to your desktop to see it that changes things.
