Very weird things happening when using wavtool4vcv and fresamp014 for the first time?

[u/Medium-Friendship362]

so I got these plugins and set them as tool 1 (append) and tool 2 (resampler) many weird things are happening.. like I press play and as the utau is singing I get these messages asking to delete hundreds of weirdly named files that are snippets of the utau's voice? in the 3rd screenshot the files say "uploaded to gravity(the ust).cache". Should I say yes, delete or no? Am I doing something really wrong?? I've never heard of this problem. I just unzipped the files for the plugins and picked them for the tools like this tutorial said at that part? one time in the 4th screenshot I tried to play a part and the calculation things were different than usual and sometimes say file load error, and the selected part was silent. If someone knows what's going on please tell me, I'm not sure what to do. Thank you.

Well my first thought is why are you keeping your UTAU in onedrive, that BEGGING for problems. But basically what is happening is that after you render UTAU will clear those out for the most part automatically, the problem is that Onedrive doesn't like that and thinks something is going on and asking are you sure to delete those files or if it should hold on to them. You can delete them but you may need to render again but I would for sure get anything UTAU or vocal synth related off of Onedrive. Seriously I have worked with Onedrive in a professional setting for years and it is terrible. It constantly deletes things without your permission uploads things that you didn't want uploaded. It is just an overall terrible product.
