number of backup is wrong presented

[GREGD]

i have snapcenter 4.3 and vcenter 6.7. 2 netapps. my retention is 31 days. when i try to restore vm primary snapshots are showing correct 14 day. when i choice option that imwant to see primary and secondary, i get list of backups for 3 months, retention is 31 days. something is not refresch correct between vcenter and snapcenter. on netapp on volume there is the right retention. 

also datastore more actions backup also number  is wrong. is more that 31 copies.

i found out that some task scheduler must run, because today sunday the numbers of backups are correct 31 item.  and this task run weekly. but which task it is i dont know.
