Widget not rendering well on modal

I'm facing a weird error that I do not uderstand. I included the widget on a blade file like it says on the documentation. I have included inside a modal but when I open it, the widgets is not rendering well. If I resize the screen, it renders well. I added the widget on a normal blade page and loads well. I tried to separate and use 2 blades but I had all in one in the past and I had the same error. If I add the widget on the first image page, it renders well. I have also acustom theme, I do not know if that might be the problem.
