when I want to enter text into a drawing template my existing drawings on the template disappear and I cant even get them back?

Hi guys,

so I am giving dimensions to some drawings in the solidworks drawing sheet. I want to add text at the bottom of the template but every time I go to open a text box to edit the information down there my drawings completely just disappear like a glitch or something. I cant even "undo" to get them back. I was wondering how can I fix this? So my drawings dont disappear and I can still continue to add my text at the bottom such as titles and part information.

Thank you!
