Probably explained that poorly. There is no option configure tank contents at all - without the reconfig in OPT I had a button next tank type and could switch between some standard fuels or no contents at all. With the reconfig this is always stuck at no fuel at all and no next tank type button.

I have a problem with the OPT Fuel tanks with Kerbalism and B9 Part Switch installed - There is no option to change fuel type as usual with other tanks and B9 Part switch. Modular Fuel tanks fixes the issue but introduces yet another UI Is this intended behaviour? Seems weird. I've looked at bit into the module manager logs and AFAIK there are some things defined based on !Kerbalism and B9 Part Switch but I dont understand module manager enough to really judge that.
