Small Business won't Open and Can't Buy Small Venue.

I changed a retail lot to a small business venue and it won't let me buy it. Then I tried saving it to the gallery, placing it on a different lot as a small business venue and it worked on the other lot.  So I saved the working one and placed it on the lot it wouldn't let me buy and it let me buy it but now it won't open.

In another instance I tried changing a retail lot to a small business it let me buy it but won't let me open it. I hit the button to open it and tried using the signs but nothing happen. So I saved it and placed it on another lot (that was never a retail lot) as a business venue and it worked. Tried saving the working one to the gallery and replacing the broken one and still can't open it.

I think there is an issue when it comes to changing a retail lot to a small business venue. I haven't noticed any other lots in my game having this issue YET. I disabled my mods and nothing is working. I don't know what to do. Is there some other way I can work around this issue?
