Modifying a bit an animation with blueprints

Hello again !
Well, I took way more time than I thought to try it… I have a question : is it possible to use two blenspace 1D in a same state machine ? Because, as I have different animations if the character have is lantern on or off for the idle, walk and run of each, I did one blenspace for each state. I tried to put my two blendspaces in the same, and with a condition if lantern on or not, but it only makes my characters move super strange (too quick and doesn’t go in the right direction).
I prefered to do another blenspace just to have the animations I want for the arm. I tried to have the blendspace with the lantern off first (as it’ll be the starting point), and then, adding each animation with the lantern on, in another state, with condition like is running or is walking, and all linked together, but it’s ugly and it doesn’t seem to work x).
And one thing I don’t understand is that I have the same thing for my two blendspaces, but there’s only the one with the lantern on that works, the other do the same strange movements that I said earlier…
Static objects are the best…

Little edit : I guess it’s the blenspace where my lantern is off that doesn’t work properly. If I have the blenspace with my lantern on at the beginning, the character move fine, but once I toggle the lantern, and switch to the other blendspace, it does this weird movements…

Second edit : I was wondering, is it possible to do it with a simple blendspace, and not the 1D ? I tried with a simple blendspace, putting the speed on the horizontal axis, and a variable I called “LanternMovement”, that I set to something like 10 when I turn on the lantern, and back to 0 when turning it off, but it does exactly the same weird movements as the blenspace 1D with the lantern off… So it seem every other blendspace I’ll create will have that, except the first I created…
