Transposing Figured Bass

Hello, is it possible to transpose a piece which contains figured bass numbers?
So far I was out of luck…
I put in simple figures (like 6 or 65). When I transposed the piece they turned into ridiculously complicated figures. I then filtered and deleted all of them and had to re-input all figures.
Is there a simpler way to do so, or am I missing siomething?

[Edit] I tried to replicate the problem to make some screenshots, but this time it does transpose fine, whilst retaining the figures/numbers. I wonder what went wrong initially…
