I would guess this stems from the fact that we unconditionally load the PMD from .well-known and security.txt. Its is essential the same PMD so the reports are generated from both.

A potential solution would add a checksum check with the already loaded one (which we have when we load the second one) and omit the validation when the sums are equal.

PR #254 tries very hard to avoid duplicate checks and there reporting.
