MATLAB: Toolbar not visible in GUI (but only when called as subgui)

guide toolbar visible subgui

I'm currently experiencing a problem in which my GUI's toolbar isn't visible when it is called from another GUI. It is visible when I run my GUI independently, however.
I attempted to fix this in a messy way just by setting both the toolbar and its individual togglebuttons to visible within the GUI's opening function. No luck, however. The handles to the buttons and toolbar exist and apparently already have 'Visible' set to 'on,' but they're simply not appearing.
There are slight differences in the GUI depending on whether it is called from another function or ran independently, but these relate only to the arguments which are passed in and the visibility setting of certain pushbuttons (not on the toolbar). Therefore, I wouldn't think these minor differences would be relevant to the problem.
Apologies for such little information specific to my situation. Not sure how to replicate this in a general sense, so hoping someone has had experience with this sort of issue or can perhaps point me in the right direction despite such a vague description. Thanks in advance.

When the GUI is being called from another GUI, is it being created as a modal dialog? If it is, then please refer to the description of the "menubar" property of figures.
