Incompatible units?

Today I struggled with the units package - again...

Let me show you what I did:

    Dynamic[Subscript[\[Tau], p]]
    Subscript[l, case]
    \[Lambda] = \Convert[Subscript[l, case]/Dynamic[Subscript[\[Tau], p]], 1]

This input results in:

    27.4889 Meter Milli
    281 Meter Milli

    Convert::incomp : Incompatible units in (281 Meter Milli)/(27.4889 Meter Milli) and 1.
    (281 Meter Milli)/(27.4889 Meter Milli)

If I don't use dynamic but constant tau_p everything is fine...
So Mathematica isn't able to to reduce this fraction? What's the reason for this behaviour and what can I do about it?

Thanks for your help!
