Question: White spot question on photo not sure the cause

[Magoun22]

Hello, I printed a photo multiple times in the darkroom and each time there was a white spot on the final print in the same place but when I checked the scan and the negative, I do not see the white spot (I have attached the scan and a photo of one of the prints I made- the white spot in the "print" is in the lower right hand corner, on the elbow). This white spot did not show up in any other photos I printed the same day in the darkroom - just this one, but again, the same place each time I printed from this negative. Any thoughts to the cause? I use an old 35mm ae-1 canon.
Print with white spot in lower right corner:

Scan with no white spot:

Welcome to Photrio.
Are you using a glass negative carrier?

Welcome to Photrio.
Are you using a glass negative carrier?

Thank you! And no, I've been using one without glass.

Is it possible the scanning software has some kind of dust removal that removed the spot after it was scanned?

If you don't see anything on the negative, that is a different mystery. I assume you checked the negative very carefully with good light and magnification?

Another mystery I would want to investigate is, Why is your print so soft (not sharp) compared to the scan?

That's the first place to start, evidently.

I'm not convinced that the two images are from the same negative frame. The hair is distinctly different in the two images as is the image information underneath the baby's right foot.

Why not try reversing the negative (emulsion up) to see if the white spot shows. If it isn't on that print it's not from the film.

Good eye @FredK. And if it turns out they are different frames, I suspect the scanned frame may be sharper than the printed frame as well.

It's just cropped differently, some shadow detail is missing in the print, which is also rather soft. I haven't tried it, but it seems to me they overlay perfectly. I see no reason at all to doubt they're the same negative.

What make and model of enlarger are you using?
Is there a heat absorbing filter above the negative holder? Maybe dirty.
Do the spots show up on the base board with no negative in the carrier?
Could mark be a reflection from something shiny near the masking frame? Chrome plated enlarger column maybe.
