  Always
  
  AutoKey version: 
  0.95.10

  If the problem is known to be present in more than one version, please list all of those.
  
  Installed via: debs from GitHub
  
  Linux Distribution: kubuntu 18.04 and others
  
  ## Summary
  
  Selecting Match phrase case to typed abbreviation also selects its opposite, Ignore case of typed abbreviation in the GUI
  
  ## Steps to Reproduce (if applicable)
  
  Define a phrase and select Match phrase case to typed abbreviation
  
  ## Expected Results
  
  Just that one option should be selected
  
  ## Actual Results
  
  Ignore case of typed abbreviation also becomes automatically selected - which should be mutually exclusive with the selected  option
  
  ## Notes
  
  In 0.95.10, if you define a phrase and select Match phrase case to typed abbreviation, it automatically also selects Ignore case of typed abbreviation which makes no sense to me. This only works one way. Selecting Ignore case of typed abbreviation does not auto-select Match phrase case to typed abbreviation. I recreated this on both front ends.
  
  I find it most curious that this bug appears in both front ends. I thought most of that code was disjoint.
  
  I  did not check which option actually takes effect, but I believe it honors the first option. If it didn't, we would probably have seen numerous error reports starting shortly after 0.95.10 was released (assuming that's where the bug was introduced - which has not been investigated.)
