Missing tool properties options

Hi there, I seem to be experiencing a different interface to the ones in the current tutorials.

In the brush or eraser tool properties window I am missing the arrow next to the preview, which shows the opacity and hardness options in the tutorial videos. Is this a case of enabling an option in the program preferences or do I need to update my version?

Screenshot attached.

Cheers if you can help.

Perhaps you checked “Flat Toolbar” on the General tab of the preferences for the software. Simply un-check this option and relaunch the program to get the original setting back with the arrow.
