I only recently bought the game (had it about a week or two now) and I've gotten a free play map to all research complete but I can't find combinators in my production list ?

what version is this from? I recently bought the game (in the last week or two) and I've got a free play game where I've done all the research but I don't have access to a few items mentioned in the wiki such as the combinator's or the personal roboport

I want to clear the personal logistics slots so I stop getting things that I no longer need to delivered but so far the best I can seem to do is to set the quantity to 0 but is there a way to actually clear the slot?

how do you get the lubricant into the assembler unit to make the Electric engine unit?
