R09110Z creating new JDE Batch by overlapping old one

JDE Batch Number got reset, and R09110Z seems to process new transactions from F0911Z1 table into Old existing Batch Numbers of same Batch type, however the Document type and company is different.

I understand we need to purge Data from F0911 data, but should not the system skip Batch numbers that are already used by same Batch type or purging F0911Z1 would resolve the issue in first place?

Please provide your thoughts on this regard.

Thanks
