Pronouncing “column” as “cullum”?

Feel free to move if this is in the wrong place.
I pronounce “column” as “coll-um”, like Gollum, with a definite “oll” sound. In this video I was watching, a woman pronounced it as “cull-um”, with an “uh” sound.
I’ve never heard this pronunciation before. She definitely sounded English rather than American/Irish, and not like someone foreign with English as a second language.
Is it a regional thing, or could it just be an individual quirk?

I too say coll um - from Yorkshire but now live in London and never heard anyone say cull um.

Well it’s an o not a u so it’s Coll-um.
The lady on your video is just weird.

I guessed as much. She also pronounced signature weirdly too (sin-ya-ture). I’m doing this admin/secretary-type course and part of it involves Microsoft Office training, the videos were on using Microsoft Outlook. I looked up the company that makes the videos and it’s a French company, but the woman sounds British. The French word for column also uses the “coll” sound at the beginning.

I've lived all over the UK and have genuinely never heard anyone who pronounces it cull-um, in my opinion she either has no idea that she's pronouncing it wrong (hearing issues maybe) or she's just eccentric
