I use the oUF-framework for the uf-layouts. The problem here is that castbar for the playerframe are not displayed in the first two layouts. The same relates to the HP bar when I'm in a vehicle. The third layout works perfectly without any issue. The really odd here is that all three layouts use the same code for the castbar and HP-bar.
To date I have not found the error and already tried everything.
I have changed nothing on the attributes, I know. If this were so, should all three layouts are not working but the third functioned properly. Both entries in the ouf.lua for toggleForVehicle are set to true.
