Google play, publishing app update, issue with 'Native platforms'

I've a hybrid app to which I've published updates in past. In current update, I've added native facebook login, which required adding facebook jar package under 'libs' folder. Now, when I add my APK in PlayStore, everything is fine except that Native platforms is being shown striked out (as shown in image). When I compare it with previous version, it shows the same but not striked out. I'm afraid publishing the update would not result in it being available on any devices. Any insights?
