Dimension tool broken again

Using Coreldraw 2019. I am continually running into this problem with dimensions in Coreldraw. I select an object and the object size is wrong. Right now it's stuck at page size of 8.5 "x 11".  The object I have selected is way bigger being about 144". I need to change the size but I can't because this tool is broken. I'm getting pretty tired of saving everything, closing every job I have open, and restarting the stinkin' program. Why does this happen all the time?
