Try select rectangle frame and see if appear or not, also try to customize items on control panel from right flyout menu and select customize.
I have done both things and that did not help either
I have updated my indesign and after the update, my frame fitting tools has disapeared.
InDesign 2015.4 has slightly larger icons to make things easier to see on HiDPI displays, and the icons closest to the left drop out of sight on lower-res displays.
The first section in this article shows the difference:
- increase your display resolution,
- buy a bigger display ($$$) or
- just remove some of the icons you don't use much from the Control panel to make room for the ones you do:
Choose Customize from the Control panel menu, and uncheck some of Object icons.
