Hi Zhongjun,
I have had the same problem with Relion. I think some programs may give masks that have a few pixels be just slightly larger than 1 (rounding errors or something), or maybe just below zero. My solution was to multiply the volume by 0.99999 and then add 0.000001
The resulting volume seemed to work then.
Good luck.
