Drivetrain 1999 Gt Clutch Release Moving Back To The Top After Just Recently Adjusting.

[OG.Sith]

Just recently bought my GT and the clutch has been my biggest complaint so far. It released near the top when I bought it, so me and my dad adjusted it to release towards the middle. It held there for about two weeks or so but seems to be releasing back at the very top again. The clutch doesn't seem to be slipping (apparently new clutch installed not long before car was traded in) plus my dad looked in while adjusting and said it looked pretty new. So not really sure what could be causing it to move and was hoping someone here would know? Thanks in advance!
