[Staking App] Current Epoch distribution shows for disabled dials

[dimsome]

Describe the bug The dials page shows distribution for current and past epoch for disabled dials.

To Reproduce Steps to reproduce the behavior:

1. Go to https://staking.mstable.app/#/dials
2. See top box

Expected behavior Dials that are disabled should not receive MTA, there is no distribution. So for the past and the current epoch it should show the correct distribution and amount
