Import issue on Optimizely CMS 12

[LongNiteco]

Hi team,

We're encountering a layout issue when using the import feature.

As shown above, the import pop-up extends beyond the screen boundaries, making it impossible to click the Accept or Cancel buttons.

This doesn't appear to be specific to version 8.2.4, I observed the same issue in version 7.5.1.
We're currently using Optimizely CMS 12.32.4.

Could you please look into this and provide a fix? Thank you!
