Double to after belong needed?


I’m not a native English speaker, and I’m unsure if here is a second to needed:

Blockers are alarms that set the state of the node they belong to to error.

LanguageTool 6.0 reports a possible mistake.

It’s okay. First to is of belong, second of verb.

LT is warning, not saying it is wrong. But it is a false positive, that could be prevented.
