We have set window and recording time… some folders still remain and wowza doesn’t delete them…You can find manifest.txt and .m4fm files - one up to three in undeleted folder… 4.7.6

Window is set and now is from 142 - 190, everything before is undeleted remains… This behavior is observed with all settings of the window and duration…
