cache clearing

hi, i'm getting some inconsistent results with the guided rule screen not showing the data objects when I restart the Red Hat Decision Platform 7.2.1 service in Windows 10 each day. clearing my space cache by deleting each of the project folders in C:\installfolder\jboss-eap-7.2\bin.index[project names] seems to help a bit, but i have 3 projects and it seems like it is difficult to get all 3 working properly again for that guided decision rule screen. i'm wondering if some one knows if there is another folder with a cache that could be cleared? if i delete and reimport the repo for the projects it seems to help stabilize things as well, but i would rather clear caches. there's a C:\installfolder\jboss-eap-7.2\bin.index\system folder that i've been avoiding. is it ok to clear that folder as well?
