Behaviour of EAT8 in ranking

Hello together, I have now switched to the new C4, as PureTech 130 with the EAT8 transmission. Now I have the following problem, if I want to let the car crawl with a gently pressed brake, sometimes I manage to, but usually that is then a bump. If you have to imagine, I drive into a very narrow parking space (there I drive slowly in ) then I try to keep the car crawling, then it suddenly stops even though I do not change the brake pressure, jet I have to get off the brake completely so that it starts up again and that is usually too fast. Start/stop is off. In short, does any of you with the EAT8 also have problems when crawling into narrow parking spaces?
