GPT Builder Bugs - Validation of URL and Icon image for GPT vanishes regardless of how many times you add it and update the GPT

The system is no longer validating URLs. I’ve spent days on this thinking it was just a propagation issue, when it is clearly now a bug in OpenAI. Also, the image set for the GPT is removed every time I add it back in, it’s gone again the next time I use ChatGPT.
