You are now getting the "Print tag" icon immediately, and no "Tag" icon, all the while when your item is still in the status ITG, is that correct?
Under the same path I mentioned earlier, can you make sure the tick box "Tag" is cleared as per the screenshot? This tick box ensures that the Tag (set status BTG) is automatically done, and the first manual action is "Print Tag" (so in fact, you go directly from ITG to PTAG)
About the approvals, I meant the nodes under
SPRO > Plant Maintenance > Work Clearance Management > Approvals
in that you should maintain and assign Approvals and check the Cross-document process if you are going to use it with your WCD.
