BUG: Investor - Programs - Invest dialog

I have just tried to invest into some Manager and i think i have found some UI bug, which doesn't allow  me to Invest into manager.

Scenario:

1. Open: https://genesis.vision/investor/programs/happier
2. Click <Invest>
3. Dialog opens with 100 GVT available in wallet
4. Next to <Amount to invest> i click on MAX
5. This returns me red message: <amount is a required field> (I thought this should calculate Maximum and enter it automatically)
6. Because MAX doesn't work like i expected it to, i have tried to enter manually.
7. In Amount to invest i enter 5. Red message changes to <Amount is more than available in your wallet> and Confirm is disabled. (Our available GVT in wallet si 100 GVT so this message should not exist in this case)
8. To resolve this problem i had to close this dialog and click Invest again. So dialog reopens and i can enter it manually.

Scenario2:

1. Open: https://genesis.vision/investor/programs/happier
2. Click <Invest>
3. Dialog opens with 100 GVT available in wallet
4. In Amount to invest i enter 101. Red message changes to <Amount is more than available in your wallet> and Confirm is disabled.
5. Then i try to enter correct amount. Example: 50 GVT
6. Message: <Amount is more than available in your wallet> stays there and Confirm button is still disabled.
7. To resolve this problem i had to close this dialog and click Invest again. So dialog reopens and i can enter it manually.
