This mod adds a lot of new items, including (but not limited to) mining drills, solar panels, crates, long-handed inserters and ore & metal compression.
Not sure if another mod is causing the issue, but the long handed filter inserter(purple) shows up in the normal inserter upgrade section and won't allow me to upgrade a long handed insert to a filter inserter version or vice versa.
I'm pretty sure there's a mod conflict here.
Could you try disabling all mods but my mod and see if you can re-create the issue? :)
