Callout does not store curve-type property

i am a new user (2 days before i purchased screenflow10) , When i customised a call out using below settings:

1) Highlighter: freehand

2) Feather: 1.0

3). In duration: 0.7 sec and out duration: 0.3sec

4) And i wanted have "CURVE TYPE" i set to Ease IN & OUT

Once i click "Style Preset" to save , so that i can re-use on multiple places on video clicp.

But i found that CURVE TYPE is not saved,
