Vst3 Plugin Acting Strange Options

[stereomax]

Summary:
Hi, I just bought TS2 - and already the first VST3 plugin I tried to use (Balancer by Focusrite) didn't work: The controls are not responding, and every time I close the plugin window and open it again the window and VST3 panel gets bigger! (fun fact: the VST2 version works)

Product Version and Format:
TS v.2.1.3

Description:

- Steps To Reproduce
Load an audio file, load the VST3 plugin "Balancer" (v. 1.0.3) by Focusrite, try to use the UI elements of Balancer, close the plugin window and open it again.

- Actual Result
The UI elements of the VST3 plugin are not responding. The plugin window gets bigger after every closing and opening again, also enlarging the UI elements of the plugin.

- Expected Result
normal sized plugin UI elements which are responding to mouse clicks.

Reproducibility:
happens every time
