Bad Distortion in SubLab Sampler

Hi.

I’ve purchased SubLab 1.1.5 in Plugin Boutique.
When i’ve try it in FL Studio 20 the sampler generate bad distortion, this distortion disappear when i deactivate option “Apply Blue Volume ADSR to Sampler”.

Where i can download previous version of SubLab?
I can transfer license from Plugin Boutique to Future Audio Workshop?

Thanks.
Regards.
