Number of app instances for licence

OS Name/Version: Debian v12.5.0 x64 (Custom minimal server install)

Product Name/Version: Professional Edition / Decadeus’ v2.4.8

Problem Description: I purchased a licence in 2019 that originally had a maximum of 5 instances but since the licence reshuffle my account now shows I have the Professional Edition but still shows I only have 5 instances instead of 15 as applicable in the licence details.

Could someone clarify this difference?
