I am working until 8 o'clock (=I am working at this moment and will continue working until 8 o'clock).
Comment:
/pe/ is predominantly progressive but it has some other uses which I feel it would be misleading to describe as either 'current state' or 'habitual'. 'I believe in God' would normally be /mo krwa daṅ Boṅdye/ but if someone had suggested that the speaker was not a believer, the speaker might reply /mo pe krwar daṅ Boṅdye/ which I would translate as 'I DO believe in God'. 'I work at the Ministry of Housing' could be rendered as either /mo travay awzing/ or /mo pe travay awzing/ but the former would typically imply that the speaker had a full-time, pensionable post at the ministry, whereas the latter could suggest that the employment was of a temporary nature.
