It's been a while, but I've worked with fsmRecord and have had no such problem.
IOW, the transitions worked as advertised, right out the box.  

It's not clear to me whether  
   field(TST0, "1")
is a valid transition or not.

It may be worth performing a "real" test for your TST0 condition, such as "pvX > 0."
Start your IOC with pvX = 0, then set it to 1.0 and see if your record transitions then.

Before trying any "real" work, though, make sure to check .STAT to see if you don't have a trivial problem with your record.

---- 
the stuff below works for me...

#----------------------------
# Initial FSM State
# checks for auto/manual
record(fsm, "$(dipole):fsm:init") {
  field(INP, "@$(dipole):fsm;Init")
  field(SCAN, "2 second") # no hurry here
  field(VAL, "YES")
  field(TST0, "$(dipole):auto.VAL PP")
  field(TRN0, "$(dipole):fsm:matching PP")
  #
  field(TST1, "$(dipole):auto.VAL PP")
  field(INV1, "1") # 
  field(TRN1, "$(dipole):fsm:manual PP") # either auto is true or not...
  # nothing else to do
}

#----------------------------
# manual state
# 
record(fsm, "$(dipole):fsm:manual") {
  field(INP, "@$(dipole):fsm;Manual")
  field(SCAN, "5 second")
  field(TST0, "$(dipole):auto")
  field(TRN0, "$(dipole):fsm:matching PP") # transition to 'matching'
  # nothing else to do
}
