Hi Sharp Studio, sorry about this, and thanks for letting us know!
Could you tell us where this happened? Was it when signing up on app.anitya.space, or when joining our Discord? A screenshot of the screen would help a lot.
In the meantime, try zooming your browser out (Ctrl and minus) or using a different browser, in case the button is just pushed out of view.
Since this stopped you before the deadline, please open a ticket in #support on the anitya Discord and we'll work out a solution for your entry. Polish week runs until 4 Nov, 23:59 UTC, so there's still time to build.
