Unable to select 1M context for Anthropic models

[cwebster-99]

Configurable options are not showing for Anthropic models in UBB accounts. They are showing for my regular staff account however and for Open AI models

I'm not able to see the context size option when Claude Opus/GPT models are selected but it's visible when I choose Claude Sonnet. is this a bug? or does it automatically default to the max size of 1M without giving user the control to choose a lower size?
