Having Trouble with the Select Shape Tool

[bliss_infinite]

I've been running into a very frustrating issue. After I create a shape using the Create Shape tool I am unable to select it with the Select Shape tool to adjust the styles. I'm not sure what I'm doing wrong and it's not always the case, but when it does function that way, I can't, for the life of me, figure out why the tool is acting this way. I might have seen a post answering this same question about a year + ago but I can't find it and don't remember the solution.

Any help would be great.
