Hello, I am using LTSpice on Mac and I have run into an annoying bug when it comes to current sources. When I use a DC Value input, I am able to check and uncheck the "This is an active load" property without issue. When I switch to a PWL file, the active load property remains on despite attempts to turn it off in the current source menu. I tried to include a video of this bug below (it's pretty low quality because of upload size constraints, apologies about that).
I have thankfully found a workaround, and that is to change the setting in the SpiceLine in the component attribute editor. However, the property flips back on if I open the current source menu.
I wanted to report the bug in case this is affecting/annoying any other users. I have also attached my model and a PWL file in case this is helpful.
