How to regard Luxembourg short-term invention patent certificate as invention patent?

Inventions have a patent protection period. The Luxembourg invention patent certificate will reflect the patent applicant (patentee), and the second page of the certificate will reflect the inventor. Due to the regulations of Luxembourg Patent Office, the order of inventors will be randomly arranged due to system reasons, and the protection period is also stipulated as 6 years for short-term patent protection and 20 years for invention patent protection from the date of application. It can be seen from this sentence that it is an invention patent.
