7-Band EQ - FilterDisplay not updating visually from script (SVF EQ + scriptnode)

[the red_1]

Hi everyone,
I'm building a 7-band EQ plugin in HISE 4.1.0 and I can't figure out how to get the FilterDisplay to update visually when controlling it from script.
My setup:

7 SVF EQ nodes inside a Script FX1 (DSP Network/scriptnode)
7 Parametric EQ effects in the FX chain (ParamEQ_LC, ParamEQ_L, ParamEQ_LM, ParamEQ_M, ParamEQ_HM, ParamEQ_H, ParamEQ_HC)
7 FloatingTiles with ContentType = FilterDisplay, each pointing to one ParamEQ effect
Knobs connected to Script FX1 parameters via property editor (processorId = Script FX1, parameterId = LCF/LF/LG etc.)

The problem:
When I call eq_LC.setAttribute(1, 500) from script, the value changes correctly (confirmed with getAttribute), but the FilterDisplay FloatingTile does NOT update visually at all.
What I tried:

Synth.getEffect("ParamEQ_LC").setAttribute(1, freq) → value changes but display doesn't refresh
Connecting FloatingTile directly to svf_eq_1 via ProcessorId → curve disappears completely
Engine.repaintFront() → no effect

My questions:

Is there a way to force FilterDisplay to repaint from script?
Can FilterDisplay work directly with scriptnode (svf_eq)?
Should I use ScriptPanel with setDraggableFilterData()? If yes, how to connect it to scriptnode parameters?
Would it be better to replace SVF EQ nodes with regular Parametric EQ effects and control everything directly from the property editor?

Thank you so much!
