Extrude alon CRV wrong direction

Hey I am trying something very simple. To extrude a HEB profile along multiple crv’s this way later in the project i can change the HEB profile without to much work. However some of the HEB profiles are extruding the wrong whay after trying for 4 hour I hoped there was some one that could help. Thanks in advance!
