1. In general, data that are interpolated in plane require x4 the disk space, process slower, and are unsuitable for tools like mrdegibbs. Unless you use that tool, you can probably ignore this message. However, if possible I would turn off interpolation for all future acquisitions.

2. I notice you also had some issues with repetition time. Were these resolved, or are there still issues? Feel free to send me a link to the DICOMs (e.g. email a link to GoogleDrive archive) if you are still having issues
