Selecting ETFs - minimum £100?

Hi,

Has something changed on the site, Now when I choose an etf for my ISA a new prompt comes up with the option to invest regularly or make a one of payment (minimum £100).

I’m sure I used to be able to just add the etf and make small investments below a £100.

Thanks

looking through some old posts this is an ongoing bug that clearly hasn’t been fixed. IE could you please help.
