preset browser is too slow

Everytime I open preset browser either for steinberg vst or vsti plugins it doesn’t display all presets right away, at first it displays some but then few seconds later it finds more presets. Especially with halion sonic se.
3rd party plugins those that have their own preset browser always are very fast and snappy and display all presets right away, no wait on having them re-scanned.
Is there a fix coming for this ?
