# Issue

**Title:** CDSL CAS: Mutual Fund holdings show incorrect (zero) current value for certain row formats

## Description
When parsing CDSL Consolidated Account Statements (CAS), some Mutual Fund holdings rows are incorrectly processed, leading to a reported current value of zero. This happens for a specific row variant where a distribution mode column (e.g., ARN/DIRECT) is present, but there is no separate "invested / total cost" column. In these cases, the row contains only three numeric columns: units, NAV, and current value.

**Actual Behavior:** The current value for such holdings is parsed as 0, which also results in an incorrect (lower) total balance for the MF-Folios.
**Expected Behavior:** The current value should be correctly extracted from the third numeric column in these specific rows, and the total MF-Folios balance should accurately reflect the sum of all holdings' current values.

## Task
