CLUTCH AND PROBLEM

Can you assist me? I own a 2019 Mitsubishi Strada. After replacing the clutch master, the clutch pedal had no pressure, but briefly returned to normal. However, after a few days of use, the issue recurred, and I'm now experiencing no pressure when pressing the clutch pedal again. Please help.

P.S U Tried bleeding it but I stopped because the air buble won’t stop and I’m halfway to my 900ml of fluid, is it normal.? To still have bubbles
