Search results sometimes show multiple buttons with same version tag and same link target

[sypets]

Example: search for "module registration api" with checkbox "12.4" checked. There are several results which contain a number of buttons with the same text and the same link:

all 12.4 buttons link to this URL: https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ExtensionArchitecture/HowTo/BackendModule/Tutorials.html#tutorial-backend-module-registration-part-1
