Unusual Fig Leaf Formation

Is anyone able to tell me why the indicated leaves on this little fig plant are emerging as heart-shaped while all other leaves are lobed, as they should be? Cheers!

 

Unlobed leaves are not unusual for fig trees, especially young ones.

 

Thank you!

 

very interesting!

 

These are typical leaf shapes of fig seedlings. Your fig seem to struggle in poor light, that's why it reverted part of its leaves to baby age leaves. It is pretty common, that sick figs push out such leaves.

 

Well, there we go. I was sitting here scratching me head. Thanks @Sulev
