Property Setter issue with Bench migrate and Git and Custom App

I added Customizations and Property Setter in my bench and added app on git…
next time when i take pull from git and migrate my bench a lot of property setters i find missing so it creates problem in my next git push for the custom app…It will remove my customization from the live as well…if i push again with missing property setters

@Srushti_Gosai Before committing the property setter changes you should export them via fixtures into your site.

i am doing all of that…in fact fixtures are there in git also…issue is in my bench when i migrate it
