NEO 2T Smart - Disc Brake Caliper pushing against black part of the home trainer depsite the use of the given spacer

Hi,

I recently got myself a Tacx Neo 2T Smart home trainer but despite using the spacer, when I set my Scott Foil RC 30 on it, the disc brake caliper is pushing against the black part of the home trainer.
Does someone have the same problem ? I've read about a bigger spacer of about 4mm, is this real ?

Thanks in advance,

Best regards,
