Without seeing you code, I can only take some wild guesses. Generally, I’d avoid using widgets inside cached functions. There is some experimental support for it, but it is just that–experimental.

If you use any callbacks, I’d also avoid including widgets there, too. Callback functions will write to the top of the page before the next script run, but whatever is written by a callback will immediately disappear.

If you could post your code or a link to your GitHub repository, maybe someone will be able to see something to point out.
