You don't need be on DL or partners, nor in a certain cabin to enter, nor is BE an issue. Quite common mistake. Ask for club manager or airport station manager if they continue to deny.
The new rule listings (effective Jan 1st, 2024) don't really make it clear that BE fare access limitation doesn't apply to Lifetime members (they only mention the ability to enter when flying partners for Lifetime members). Not clear if it is just sloppy wording by DL. But I could see DL agents interpreting new rules as no access on BE fares even for Lifetime members.
