Database sequence value decreased after MariaDB upgrade

Our environment is mariadb galera cluster with 3 nodes (node1 +node2+witness), Current db version is 10.6.22, while we performed rolling upgrade, patching node2 to 10.11.15 first, Keeping node1 still 10.6.22
Then when completed node2 patching upgrade, and switch application traffic direction to node2, Encountered the very serious problem , the database sequence value decreased huge, by the way, our traffic are always direction to node1 at past:

• sequence: seq_abc_obj_xxx_id
• value at node1(10.6.22) not DB upgrade: > 7,635,954
• value at node2(10.11.15) after upgrade: <* 1,770,744*

#1. show create table seq_abc_obj_xxx_id : the desc is same as node1 and node2
CREATE TABLE `seq_abc_obj_xxx_id` (
`next_not_cached_value` bigint(21) NOT NULL,
`minimum_value` bigint(21) NOT NULL,
`maximum_value` bigint(21) NOT NULL,
`start_value` bigint(21) NOT NULL COMMENT 'start value when sequences is created or value if RESTART is used',
`increment` bigint(21) NOT NULL COMMENT 'increment value',

`cycle_option` tinyint(1) unsigned NOT NULL COMMENT '0 if no cycles are allowed, 1 if the sequence should begin a new cycle when maximum_value is passed',
