All of the vias are 0.3 mm hole and 0.4 mm pad. This leaves only 0.05 mm for the annular ring.
The drill holes are never aligned perfectly so they can leave the pad or cut the connection between the track and pad. See here.
JLCPCB recommend 0.2 mm minimum annular ring (0.3 mm hole, 0.7 mm pad). There should be enough space to change all the vias to that size.
